33 Truly Bizarre, Nightmarish House Guests Who Will Never, Ever, Ever, Ever, Ever Be Invited Back

We covered a Reddit thread by u/Jentenny99 where they asked people to reveal the weirdest thing a guest has ever done in their home. That post seemed to resonate with BuzzFeed Community members because they began sharing their own nightmare guest stories. Here's what they revealed:

1."My brother-in-law and his wife had a huge, totally untrained German Shepherd. We had a 2-year-old who was terrified of dogs and had asked that they not bring it when they came to visit. They agreed but showed up with the dog anyway. We had a storage building, and said they could put the dog in the storage building. It was Thanksgiving in Indiana — chilly but not freezing — and we thought the storage building was a good solution. They brought the dog into the house during the night. It got into the trash, dragged it all over the house, and ate some used disposable diapers, which it then vomited back up all over the house. We awoke to a mess and a screaming child. They and my husband's parent thought we were being unreasonable for being unhappy that they ignored our request."

2."Once, two former, very religious friends dropped by my place unexpectedly. We were chatting in the kitchen when the wife wandered into the adjacent dining area and began reading a letter I had left open on the table. This letter was from a high school friend who had recently gotten married (she's a lesbian) and had sent some wedding pictures. The wife saw the pictures and began screaming, which made her husband rush over. They immediately began mocking my high school friend. I got angry and told them they had no right to read my mail or judge my friend. They quieted down and apologized, but then the husband asked, 'So, which one is the man?' and they both began to laugh uncontrollably. At that point, I was so furious that all I could do was point to the door."

3."My mother-in-law lived with us after she had lost her job and sold her house immediately at a loss. She repotted all my plants and stuffed them into pots to 'save space.' She cut up our good laundry towels because she needed rags for her art (even though we had a bag full of rags in the garage). She gave me $100 every two months to cover her expenses (her portion of electricity, rent, food, etc.). She used my measuring cups to mix her glue for her art. Finally, she complained to her son about how I didn't keep the house very clean, even though I was working full time plus overtime and taking night classes while she and her son worked part-time and did nothing else."

4."My brother and his wife came down on July 3 to spend two nights for a family 4th of July party. I fixed a nice dinner and homemade dessert that night, and they stayed in our very nice guest room. I fixed a good breakfast in the morning, and we were preparing for the family event. My brother was trying to use my quirky little electric can opener and couldn't get it to work, and was complaining about it not working. He is extremely narcissistic and insisted he was using it right, but that it was broken. When I told him it worked fine and that I would show him how it worked, he exploded into a rage, spouting extremely obnoxious curse words, screaming at me and my fiancé, with whom I lived, and said he was leaving."

"He instructed his wife to leave and then took his cooler, which we had filled with beer and other drinks for the party, and dumped it all out on our floor, ice and water everywhere, all the time screaming curses like a madman. He was like a demon possessed. They left, and I haven't spoken to him since."

—Anonymous

5."A friend was visiting us, and we watched a movie in the living room. The friend disappeared, and when we finally looked for him, we found him removing food from our fridge and putting it into his bag. When asked why he would do such a thing, his response was, 'I was there when you bought it.'"

6."We hosted a wedding at our lakehouse home. While waiting for the ceremony to start, the groomsmen drank all of my husband's beer from our bar fridge and sat ON our kitchen counters. They tossed beer caps into our sink, so I had to fish them out of the drain so they wouldn't break the disposal. There's a trash can IN the kitchen; it's not hidden. There are plenty of chairs at the table to sit in. These were GROWN men."

7."A high school friend of my husband's had asked if she and her family (boyfriend and 5-year-old daughter) could stay at our house for a couple of days while they were in town. I didn't know them, but I was okay with it. They showed up with a car full of stuff; it looked as if they had been living out of their car. Of course, a couple of days quickly turned into a week, with no end in sight. I quietly gritted my teeth when I saw them sitting in my guest bed, eating nachos while their daughter ran wild and making big messes for me to clean up. Then, one day, they had a big argument, and the boyfriend took off with their daughter, leaving behind the girlfriend/mother without her wallet (deliberately). She had no money, ID, or car, and apparently nobody was willing to take her off our hands."

"For the following week, she lived at our house, depleted our booze supply, and generally drove me nuts. Then, after a week, the boyfriend showed up out of the blue, and they kissed and made up. I walked downstairs to see him carrying multiple suitcases back upstairs into my home, while she was starting a bath for the kid. It was clear that they were planning on moving in for a long while. I freaked out, ran to my husband, and suggested that we give them money for a hotel or whatever it would take to get them out of my house.

We confronted them, and thankfully, they agreed to leave without a conflict. Surprisingly, they didn't even take the money. I felt bad for the kid, but I knew they had a large extended family who could/should be helping out, and I already had two young kids of my own (who were quite traumatized by the whole series of events)."

8."My brother-in-law was visiting friends in Florida. He always wore a thong but took it to a new level when he decided to grab a morning coffee in the kitchen, Winnie the Pooh-style (no pants, T-shirt). Our friend's wife entered the kitchen and was shocked to see him standing there, calmly drinking coffee. Also, he sunbathed nude in the backyard and sunned himself on the floaty in the pool. Their neighbors complained. I hope they burned all the furniture in the backyard."

9."An old friend, whom I had not seen in years, visited me for about a week. About two-thirds of the way through her visit, the pipe in our only bathroom burst, and the plumbers told us to use buckets of water to flush the toilet. When I told my guest, my guest said, 'Oh, that's okay. I just peed in your mug and dumped it down the sink.' I asked her not to do that again and to use the bucket instead and fill it with water to flush. She then said to me, 'But urine is sterile. I've drunk my own urine before. Monks do it all the time.' Needless to say, I was speechless."

10."A fairly new friend I'd been hanging out with frequently was letting a friend of his from out of town have his one-room downtown apartment for a handful of days. My roommate had recently moved out, so I invited my friend to stay at my place in the burbs. I gave him my room and slept on the couch. I knew he had a drinking problem, and some red flags were building up, but he was polite during his stay, and we got along well. He apologized for running out of time to wash the bedding when he left. I said no problem, but when I went to wash the sheets, I found he had been humping my pillows, a lot by the looks of them! I washed everything twice, threw out my crusty pillows, and ended the friendship. Dude, I put my face on those things. How would washing my pillowcases make that okay?"

11."A friend's son, wife, and 16-month-old child came to escape the heat. He told us his wife would be working and needed a quiet space every day. We gave her an extra bedroom. We gave her an extra bedroom. That lasted a few hours. She used every room, ignored the child all day, took tables, lamps, and even drawers from a desk in one of the rooms, and piled everything on top of each other in the closet. She did not put the room back together. Every morning, they would go out and come back with coffee, and she would eat something hidden in a little bag. They never asked us if we wanted anything or offered to take us out for a meal or contribute a single thing. To top it all off, she hid my dog's favorite toy in a Halloween decorations box in a closet. I discovered it last Halloween! It was so easy saying no to their request to come back for a few days this month, now with a 3-year-old and a 5-month-old. They are extremely wealthy but clueless."

12."Around 20 years ago, my (now ex) husband's brother was moving from California to New York and asked if he could stay with us for three days between when he gave up his apartment until he was scheduled to leave. No problem. He didn't mention he'd be bringing his cat. I was highly allergic to cat dander. Tears would stream down my face from the time I got home at night until I left for work again in the morning. I bought some Benadryl and decided to tough it out because it was only for three days. Six months later, he was still there. He made a mess, was disrespectful of our need for sleep, and never cleaned or contributed in any way, even though we both worked full time while trying to get our own business off the ground."

"When we told him he had to go, he said he realized taking the cat on the cross-country road trip to New York wasn't practical. He said if we didn't take her in, he'd have her put down, have her cremated, and take her ashes with him in a coffee can. Obviously, I wasn't going to let that happen, so…we got a new cat. Strangely enough, my allergy to cats abated over time, and I now have two of my own. At least there was a silver lining."

13."One of my son's friends' girlfriend came over to my house for a few drinks. When I left to use the bathroom, I came back to the kitchen to find her with her pants down and peeing in the sink! WTH?!"

—Anonymous

14."I gave a young friend a wedding shower. I'm a pretty good cook/hostess, so I went all out on the food and drinks. I set up a buffet with many choices and a drink station (no alcohol). My friend's future aunt was in front of me at the buffet. She ate a chocolate-covered strawberry and put the stem on the buffet. I didn't say anything until she tasted a dip and then put the spoon back in the dip. I was furious. I told her to pick up the stem and put it on her plate, and if she wanted to know how something tasted, she should put some on her plate and use her own spoon to taste it from there. Of course, I removed the dip."

"A short time later, I heard cupboards opening and closing while everyone was eating. I entered the kitchen to find the aunt opening and closing my cupboards. I asked her what she was doing, and she said she was looking for a coffee cup. I told her there were coffee cups at the drink station. Later, I heard cabinets opening and closing again. I went down the hallway to find her snooping in my cabinets. I told her to sit down with the guests, and I would ask her to leave if I found her snooping again."

15."In my early 20s, after college, a few friends and I had an apartment in Boston. One of our other close friends lived at home after college but would come and stay with us during the weekend and stay over after hitting the bars/nightclubs with us. He was usually a good guest. However, after a while, he got too comfy at our place. One weekend, he got sick from drinking too much, puked on our wood floors, and cleaned it by wiping it up with old newspaper. No soap or cleansers! Another weekend, he held a party at our place for some of his other friends without asking for our blessing or inviting us! He just had guests come over for a party he threw at our house!"

16."Some family came for Thanksgiving for the first time. They brought their dog (without asking...and we have cats) and lots of drugs. The entire five days were a drunken drug fest with their dog lying all over our furniture and in our bed and chasing our pets. They were drunk and stoned the entire time while fighting and giving each other the silent treatment. Happy Thanksgiving. Never again!"

17."My partner's daughter came from out of town and stayed with us. She is over 40 and rudely bossed her father around every day. She stayed in our guest bedroom, which had been my deceased daughter's bedroom. I kept many of her things in the dresser and closet. One morning, she came downstairs and informed me she was bored the previous evening and went through all my daughter's belongings. She had the nerve to ask for a Gucci handbag that she had taken down from the top shelf in the closet. I was speechless and asked for an apology. Didn't happen."

18."Friends of my ex-husband stayed with us between moving houses. I came home earlier than expected and found the wife leaving with a cooler of meat from my freezer. Her sister was 'facing hard times' and needed it. They could have actually stayed with her because she had room, but our place was 'nicer.'"

19."My ex-roommate invited a friend to sleep on our couch for a few weeks…without asking me first. I went along with it despite the rough start. The guest decided to help herself to our food and constantly left the front door unlocked, so I counted the days until she was gone. One Saturday morning, I was rudely awakened by the sound of a vacuum running before 6:00 a.m. However, my vacuum was still broken from the last bad roommate! I walked into the common area to see the house guest blowing up my air mattress with a strange guy. They popped my air mattress before 6:00 a.m. on a Saturday!"

20."A relative of my foster mother's would come over whenever she liked and tie up the phone for hours. Even if no one were home, she'd let herself in (doors were never locked) and go straight to the phone! If we were home, no one was allowed to do anything other than sit still and be quiet until she finished. Bathroom trips were the only escape allowed. It was considered impolite to leave while she was on the phone!"

—Anonymous

21."My best friend from high school and her husband asked if they could stay with us on their way from Florida to northern Michigan. It was no problem until I came home from work to find she had gone through all my drawers and jewelry and set aside pieces she wanted me to give her! Her husband warned her I wouldn't like it, but she assured him we shared everything. I was mortified at the invasion of my privacy and snatched my things up. She kept bugging me to give her a certain pin. I was really mad. That was the last time I left her alone in my home."

22."We met a seemingly nice couple while traveling in Turks and Caicos. We dined and visited a few places on the island since we had a rental car. The other couple was staying a day longer and wondered if we wanted to leave the car with them. Uh, no. We needed it to get to the airport. The next thing we knew, they said they would be traveling through our town and suggested they visit us. We accommodated them, and even though they knew we had a 14-year-old son at home, the wife traveled back and forth from their guest room to the bath next to my son's room in a bra and underwear. Not appropriate!"

—Anonymous

23."My husband's cousin and his wife stayed with us for nearly a week. They had bottles of cheap wine in their suitcases and drank continually. We bought and prepared all the meals and would open a bottle of wine, but we were lucky to get one glass before they finished it off. Everywhere we went, they would stand back from the cashier, even when visiting a museum that they requested to visit, and would wait for us to open our wallets. They insisted on dropping into Trader Joe's before they left to buy as many bottles of cheap wine as they could fit into their suitcase. We did speak to them about their drinking, but they shrugged it off. I don't know which was more annoying, their unwillingness to offer to pay for anything or their unwillingness to open a bottle of wine and share with us. We stayed with them previously and paid for everything, by the way."

24."We lived in the country and had a beautiful view. One of my husband's work colleagues asked if she could have her 'very tiny' wedding at our house because it was her dream setting. She promised it was just a couple of immediate family members. Turns out there were over 100 people. We came home to patio furniture in the pool, not one sheet remaining of our toilet paper or paper towels, ruined bath towels, a backed-up septic system, mud all over the kitchen countertops, and a garage filled with trash. I wouldn't treat a cheap motel that badly!"

25."When I was a kid, whenever we went on holiday, my grandma would pop in to feed the cat, water plants, etc. We'd return every time to find she had rearranged the living room furniture! The first few times, my mum was furious. After that, it became a running joke. She would move stuff around, but only little things, to see if we'd notice. It's still a bit annoying, but much less so than having to re-rearrange the living room when you've got a bunch of holiday laundry to deal with!"

26."Against my better judgment (and the advice of my own mother), I let my sister, her husband, and her young son stay with us when they lost their apartment. They had lost multiple apartments because they would stay without paying rent until the landlord figured out a way to kick them out. But she was family, and I couldn't turn her away. While there, they would hide their own food in their room, but eat all our food. At the time, we were installing wood flooring in the living room, so the rule was that there would be no eating or drinking in the living room. I would get up in the morning (because I had to go to work early, so they were still up when I went to bed), and there would be the wrappers from Icy Pops in the living room, so obviously, that rule was ignored."

"I confronted my sister about it, and she said her husband thought that our rules were too strict! Also, our bathroom sink wasn't operational, so my brother-in-law helped himself to one of my Tupperware dishes. He filled it with water from the tub and set it in the sink to use for shaving because he couldn't manage to shave without a mirror.

After about a month, we had had enough of it, and I told my husband he could kick them out (he had wanted to for a while but acquiesced to my wishes because they were family). They must've sensed that something was happening because they hid in their room with the lights off to avoid speaking to us. Finally, one day, I took our kids and left to take them to a park, knowing they would leave their room after they thought we were all gone. My husband said that we had barely gotten out of the driveway when they emerged from their room, and he told him that we needed them to leave. My brother-in-law accused him of putting his son on the streets, and my husband said, 'Your son can stay, but you and your wife have to leave.'

He watched as they moved their stuff out because we didn't trust them at all, but our brother-in-law had his own idea of revenge. After they were gone, my husband discovered that my BIL had gone into the bathroom just before they left for the final time and urinated all over the whole bathroom: the sink, the tub, the walls, the floor, the ceiling. It was everywhere. That's what you get for being a good person."

27."My husband's aunt and teenage cousin asked to stay with us for two nights (Sunday to Tuesday). I wanted to make them feel welcome, so I made a big dinner both nights, complete with homemade apple pie and crumb cake (my specialty). I also made breakfast and lunch for them, and rescheduled my 2-year-old daughter's gym classes so I could spend time with them. Things were okay, but my husband and I were slightly disappointed because they were sloppy, ate all our food, etc., and never offered to contribute anything. The cousin actually drank an entire gallon of milk and ate all of the homemade chocolate chip cookies I had made. When I asked the aunt to watch my daughter while I ran out to buy more milk, she said no!"

"Shortly after my daughter and I returned from the store, the aunt informed me that they planned to stay again that night. I said that was fine, but that my daughter and I had an early morning gym class, so I asked what time they planned to leave in the morning. This angered the aunt, and she accused me of putting them out on the street! I let my husband deal with it, and his uncle (aunt's brother) came to pick them up later that evening. The aunt hadn't wanted to stay with her brother because our house was nicer. My husband never allowed them to stay again."

28."My mom used to have a bestie from school days. At some point, her friend and her adult friend's son stayed with us because he had to apply for a military school in our city. Long story short, they stayed the entire summer, they wrecked our phone bill, they had the AC on 24/7 ( of course, never did they pay for anything ), and when they finally left, her husband suggested that my mom and I stay in one of their summer houses (they were extremely wealthy) during our hollidays. We accepted it, but her son decided to let his pit bull attack my dog during our stay. I rescued my dog at the last minute, and I told him that he was mean by nature and a douchbag. We stopped talking with them until my mom died. Her friend came to the ceremony, where she decided to tell me that my dead dad wasn't my real dad and that my dead mom should have told me years ago. By the way, my face is identical to my father's."

29."I don't know if this counts as a house guest because it was someone I met at a bar, took home, and haven't seen since that night. I don't even remember his name or if I ever knew it. Lucky for him, because he somehow ordered hundreds of dollars worth of porn on my cable TV account at some point?! I guess he did it while I was using the bathroom because nothing else about that night was good enough to hold my attention long enough for him to do that unnoticed. Lucky for ME, Comcast gave me the benefit of the doubt and refunded the charges because I had never ordered anything like that before."

30."When my husband and I moved into our new house, my brother-in-law asked if his family (his girlfriend, their kid, and their dog) could rent out the basement until they had saved up to get an apartment. We said okay. At first, it was okay. Then, their dog got pregnant because they hadn't spayed her. She gave birth, and they didn't lift a finger to help with seven pups. My husband and I paid for all the food and vet bills. We raised, cleaned, socialized, and found homes for them. That's only the start. We asked them to use the shed outside to smoke weed and not smoke in the house. They didn't care. They not only smoked inside, but the girlfriend smoked 24/7 until she made herself physically ill from so much weed and vomited all over our floor. They both refused to clean the puke and let it sit for days until my husband cleaned it. This happened multiple times."

"Then, they bought four or more fish tanks and filled them with fish. The tanks leaked all over the carpet in their room, which created mold. The fish died of neglect. Our basement reeked of weed, vomit, mold, and rotting food. We tried to work with them for their kids' sake for a while, but things got worse. They fought and screamed at each other every night. They lied and stole from us. We finally had to kick them out. They abandoned their dog with us.

In the two years since then, they've been couch surfing at different houses until they get kicked out of those, too. They've had two more children. Child Services has been involved and has done nothing. We got a cool dog out of it, at least. Oh yeah, and they never did pay the rent."

31."My wife's sister, who lives 11 hours away, likes to travel. She has money and occasionally talks about how much she has in the bank. Travel is a fun pastime, but instead of hotels, she regularly finds distant relatives, friends, etc., to stay with. Last summer, she rented her house for a week, so she had no place to stay, and then asked if she could stay with us for a few days. We said no problem. After the first three days, she asked if she could stay longer and if her son could come too and sleep on the couch for a few days. Once again, we said okay. She then added that her son's new girlfriend would also be staying. The short stay turned into a week. Despite having money for dinners, drinks, etc., they never contributed to any food. My wife accepted this behavior since her sister has always been like this."

"Finally, the week ended, and they left. About a month later, a similar request came, and the sister asked to stay for three days. At the end of the third day, my wife, her sister, and I were having our morning coffee when I politely mentioned that the past three-day visit was much better than a week. She exploded, began crying, then left. She has not asked to stay at our house since."

32."My live-in boyfriend at the time invited his friend and his friend's family of four (plus two dogs) to stay at my two-bedroom apartment for a weekend. Mind you, he did not pay rent or share any household expenses. I politely reminded him of my apartment complex's no-dog rule and expected him to tell his friends to stay elsewhere. I came home from work to find them, their dogs, and their luggage in my living room. I reluctantly set up the air bed and kicked my kid out of her bedroom so they could stay in it."

"The dogs dragged their butts all over my carpet, spreading poo stains everywhere. The friend's fiancée mentioned relentlessly that she had a graduate degree. Half the people in our house did, so it wasn't a big deal. If her degree was worth anything, it could've paid for a hotel. Their kids paid my daughter no mind, even though she tried to be friendly with them. If I noticed my kid, a guest at someone's house, was being a snob to the owners or kids of the house, they would've been reprimanded real quick.

Weeks later, they dared ask if my kid would be in their wedding. I'd never met them before that weekend and never spoke to them again. Needless to say, I'm not with the old boy anymore and am grateful not to have his friends in my sphere."

33.And: "We met a middle-aged, single, Australian man while on a trip to Britain. Two years later, he called to say he was coming for a visit to Canada. We told him clearly that I, now working full time, was also dealing with both my mother and father in the hospital, who were dying. We had no idea that he intended to crash with us for free for three weeks, and he expected his meals on time, his laundry done, and free transportation everywhere, to whatever he wanted to see. He was also continually rude and abusive to my husband, who was only attempting to get him to pitch in for costs and allow me precious time with my parents. Our future travels have not included sharing addresses or phone numbers with others we meet."
