Attended one yesterday as a bridesmaid. The brides cousin was also a bridesmaid, spent the whole morning clearly aggrieved that the day wasn't about her... smoked in the getting ready suite and had to be told to put it out, then lit up again and claimed she had forgotten when the bride told her and made a snarky comment..then presented her silver converse she had customised to wear with her dress as she "doesn't really do heels"... the bride ignored her and sweetly said "at this point I don't think I can stop you" as she knows what she's like then what do you know, she wears the heels! There were loads of instances like this all day and she is 28 but seemed to want to just be am inconvenience all day which I assume was jealousy...even little things like being late for photos and pretending not to hear when called over, pushing the food round her plate, really ungracious behaviour. The wedding was fantastic! She could have really enjoyed it much more. Not really an aibu but whats the worst behaviour youve seen like this?

Bridesmaid at my aunt and uncle’s wedding- I drank repeatedly from the bridesmaid glass by mistake all through dinner, sang a song about a bird spinning round and round my plate at full pelt, fell off my chair and had to be put to bed.

1973, I was 3 and had been necking blue nun

Late 1980s winter wedding. The bridesmaids dresses had been hired and had very short sleeves.

Once we got to the hotel for the reception there was sherry as a welcome drink.

More than one adult gave the youngest bridesmaid a sherry to 'warm her up' 7 year olds have no idea that they are supposed to sip and not neck a drink. One tipsy bridesmaid.

A wedding where the day before the reception they phoned to say the room was double booked.

When we got there there was supposed to be mulled wine on arrival, there wasn't and the bride was about to melt down. I had on my 'Bolshy boots' so I went to find a manager. I went in the bar and asked the server to get the manager. While I was waiting some bloke stood beside me and ordered a beer, "On the wedding tab", well my bolsh decided that was not on, I asked him if he could name either the bride or the groom? I told the server no one from the wedding was in the bar yet. I wonder how often that guy has free drinks from wedding parties.

When we checked out someone had charged a meal to our room. And the hotel tried to argue that we had eaten in the restraunt.

At an adult only wedding, the MOB invited her friends with their 5 year old to the evening do. The friends brought their daughter in what could easily be a wedding dress.

The groom and mates arrived at the church straight from the pub. Announced that he needed a piss, whipped it out and did it in front of everyone up against a grave stone.

RawBloomers · 09/02/2026 06:08

I used ot be apolice officer and responded to a stabbing at a wedding once. It was the bride's dad who stabbed his brother!

For wedding's I've been a guest at - I went to one where the bride's dad seemed to spend the entire time putting his wife down. The bride ended up being a bit of a disaster as a wife (I was a friend of the groom) but from what I witnessed at the wedding I'm not surprised. I can't imagine growing up in a home where your dad talked about your mum with such contempt could really be conducive to developing good intimate relationships.

The father of one of the grooms did a speech and he just talked about how his awful it was that his son didn’t have a wife he was also racist towards his sons husband, he was quickly removed and my friend the groom never spoke to him again.

At one wedding the mother of the bride and the brides aunt were caught doing cocaine in the toilets, they had tried to sell some to a waiter so the police were called and they were assested for supplying and selling drugs. The mother ended up in prison, her house was searched and it was clear the drugs on the property weren’t for personal use, unless she lived with a coke addict hoover.

My husbands parents turned up to ours (they weren’t invited), luckily venue staff has been pre-warned about them, a few guests were fairly merry by this time as well, my elderly great aunt told them to go and fuck themselves. I’ve never heard her ever say anything rude about anyone so I was both shocked and proud.

A work colleague invited his former step mother- the OW from his parents marriage. Apparently she is nice and really helpful during A-Levels /College.

Hi dad got back with her at the wedding! His poor mother, and he had no clue why people were shocked.

mjf981 · 09/02/2026 06:50

When I was 14 my Dad took me to his good friend's wedding (my Mum was away with work).

I befriended the bridal party and spent the time between the ceremony and reception doing shots of rum in the parking lot with them (it was that sort of wedding..). Needless to say I was rapidly legless and vomited all over the door to the venue. It was the first time I had ever been drunk and the hangover was epic. My Dad thought it was funny, and to this day we've never told my Mum.

@FlappyThing I need to know did he butter the roll or his penis?

honeylulu · 09/02/2026 07:06

This thread brings a whole new meaning to the term "a knob of butter".

At a friend's wedding the groom put a pool table through the window at the evening reception then proceeded to put all the buffet leftovers into a black bin bag in case he got hungry later. I called to their house the next day and they were arguing over the bin bag. He tried to get me to convince her that the mangled mess was still edible. They're divorced now.

At DP's nieces wedding we overheard MOG talking to her sisters about how it wasn't such a disaster because DN actually scrubbed up quite well. That would be DP's niece, the model.

How did one man lift a pool table?

James Corden walking around the reception area (wedding at big posh hotel - he was a hotel guest, NOT a wedding guest) talking very loudly into his phone, making sure everyone could see (and hear) him!

He is annoying.

MantleStatue · 09/02/2026 07:30

I've said a few of mine on MN before.

Cousin's wedding. She had a sister who always had to be the centre of attention. Sister said as they were all getting ready 'If i faint this will be my day, not yours' with glee. She subsequently did the most delicate lady-like 'faint' during the speeches where she was able to carefully ensure that she didn't end up in the soup. Then got up and yelled out to everyone 'Well, she might be married, but I'm pregnant'.

And one where the best man gave a speech saying 'women are like frying pans- you have to warm them up before you put in the fat'.

My own wedding where one of DH's friends shoved bottles of champagne from the tables into his jacket and his wife's bag and hissed at us 'Go grab some champagne... it's FREE' (no it wasn't- we were paying for it).I came to realise that he has form for cheating. When we would go out for dinner we would split the bill but he'd pinch the receipt saying he'd 'claim it on expenses'.

SaturdayNext · 09/02/2026 07:36

My cousin has had three weddings. For one of them, her mother had bust a gut making the bridesmaid's dresses and the cake, and had done lots more to help. Groom's mother did nothing. Groom used the whole of his speech to bang on about wonderful his mother was, no mention of the bride or her mother.

Guess what, his view of the purpose of marriage was basically that his wife would look after his mother. Reader, it didn't last.

howrudeforme · 09/02/2026 07:36

In the early ‘80 some distant relative (groom) marrying a girl his parents didn’t like. So only about 15 people in the room and the bride had to wait outside on the fire escape and only allowed in for bits of the ceremony. The family treated her appallingly and her mum and dad could only sit there and watch on.

BlossomLeaves · 09/02/2026 07:44

DH’s best friend at our wedding, for context he’s never liked me but was invited anyway.
Lots of little irritants during the day like moving place settings, being rude to guests etc but the one that endures was him sticking his fingers up to the camera on the background during our first dance ruining all the photos. We don’t speak to him any more…

Oldglasses · 09/02/2026 07:48

FIL got up on stage w the band and started singing.
Not ‘bad’ behaviour but totally cringe (was my wedding!).

MySweetGeorgina · 09/02/2026 07:48

My best friend at our wedding was Maid of Honour and wanted to choose her own dress which was fine with me

it was a low key wedding in the back garden and local church, so not a big formal do.

she wore a red mini dress which some of the guests thought was off. I did not care at all, looked pretty cool in the photos too, but my MIL and in-laws still talk about it 20 years on 😁😁

Name begins “Sir”.

Studied at Cambridge.

Has hosted many tv series & had many books published… had a bit of a media fracas a good while ago following some ill-judged/offensive comments, but career very much continued…

Probably several candidates with that kind of behaviour, to be fair 😊

Dollymylove · 09/02/2026 08:10

Reading this mostly hilarious and sometimes very sad thread, I have concluded that the mumsnet view that seems to paint men as always the problem with horrible behaviour is a myth .
Women are just as bad, especially when copious amounts of (free) alcohol are involved 🤣

Groom was a no-show. Bride in tears at reception (which went ahead)
Best man so pissed his ‘speech’ was a car crash

My wedding . Sat on the loo when I hear an almighty argument/ fight start outside the stall. A friend of DH's had just discovered his wife shagging one of the catering staff, catering staff's girlfriend ( also working ay my wedding ) followed her into the ladies loo to confront her. An honour guard of my female relatives pulled them apart and got me out of the loo. All parties then invited to leave.

I did a google - my conclusion is Attenborough as others have been guessed and dismissed. I hope it’s not.

No fighting and probably tame but this still pisses me off over 6 years later.

It was DH and I second marriage we had around 50 guests to a lovely hotel where we also had the ceremony. We had two long tables and on our table was all of our nearest - our kids, parents, DH Grandchild. As anyone who has planned a formal sit down meal knows you can agonise over the seating plan and DH wanted his DD and Grandchild opposite us on the table. We walked in to the meal to find that his 'D'D had totally changed the seating to put herself and Grandchild at the end of the table. Now sitting opposite us was his other DD (who is lovely) with her weird new BF who sat bang opposite me and next to my Mother. He didn't speak a word to any of us and sat there with a face like a slapped arse throughout the entire thing. He is on all of the photos of us giving our speeches, I still seethe whenever I look at them - imagine going to a wedding and switching the seating around.

DH Daughter has form for thinking the world revolves around her and I wonder if I had moved her top table around when she married a year earlier how it would have gone down. Like a cup of cold sick I imagine.

kavalkada · 09/02/2026 08:35

I’ve been to several. At one wedding where I was the maid of honor, I fainted right before the bride said “I do.” It was very stuffy in the church and you could barely breathe. I didn’t even know I had fainted until I saw the photographer and the priest throwing holy water on my face.

At another one, my cousin’s husband grabbed me on the dance floor and deliberately, roughly put his hand on my breast — not by accident. I slapped him, after which everyone told me that I know what he’s like and that I have to understand it.

At a third wedding, the groom got drunk and, at the moment when he was supposed to use a knife on the krokant (a cake that is broken at weddings in my country), the candle turned and caught the bride’s dress on fire, so we had to pour water on her.

Bikergran · 09/02/2026 08:36

Over 52 years ago, my dad's cousin, as she came up to me in the receiving line on MY wedding day, said "You look very tired and pale, dear!" What obnoxious bitch says this to a bride? My mother said later that apparently she was always jealous at weddings as hers had been a hurried wartime registry office do. If I'd known, I wouldn't have invited her. She's dead now, and it STILL annoys me!
