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?

The father of the bride gave a speech about himself and thanking some of the venue staff but not mentioning his daughter, my wonderful, successful and incredible friend. We agreed after that I should have done the speech and to this day I am a bit peeved that I didn’t do an extra one. Twat. He had always been a toxic parent.

Best man shagging bride.

JeannieJo · 08/02/2026 22:23

I was about 14 and at my cousin’s wedding. It was a free bar. I still have a vivid memory of a woman crawling out on her hands and knees and crawling up the road…

OnarealhorseIride · 08/02/2026 22:23

Need to add, did not actually see this, heard about it afterwards.

A relative of the bride was an amateur photographer and was very put out that they didn't ask him to be photographer for the event. He turned up with a massive professional camera anyway and spent the day in a sort of weird competition with the actual photographer, like something from a sitcom.

I have a similar story - bride’s cousin was an amateur photographer and asked her in advance if he could bring his camera and take photos alongside the professional they had hired. Sure, no problem.
After the wedding he emailed them the photos he had taken with a huge watermark over them and said “I’ll take £5 per photo you want” 😂

Tame compared to many here, but massively amused my DW and I.

Shared a table with a couple at a recent wedding who seemed nice enough, although they did the cardinal sin of hijacking the table's wine leaving us without a look-in.

Quite early in the night they very clearly dragged each other to the loos for a quick shag, emerged quite shamelessly and obviously afterwards, him with a massive smile on his face and her looking very much as though she had been dragged through a hedge backwards, but clearly equally content.

An overheard comment from one of the small children at the party just made it, 'Daddy look, she must have been unwell but he took her to the toilets and is better now."

This isnt at all funny, plus trigger warning for SA.

FOB seemed very pleased with the extended metaphor in his speech, which painted his daughter as an expensive motor car; sleek and aerodynamic, great upholstery, turns heads, etc.

A fair few people at the wedding knew he had abused both his daughters during their childhoods.

Many years ago, an old friend was the plus one for a MoB on a TV series, Don't tell the Bride. He said that the groom had an interesting family and somewhere there is a recording of the Groom's family kicking off at the reception after the cameras allegedly stopped rolling. He said it was a busy evening for him, as back then he was a Consultant in A&E... and he had not expected to be working that evening!

AChunkOfPurestGreenMilady · 08/02/2026 22:35

A mate of DP's wedding where two middle-aged women in twinsets and big hats had a fist fight in the car park, and another where someone got stabbed in the leg with a fork ( that one had a medieval theme and a lot of guests were in costume so it could have been a lot worse! )

I feel chipolata bun man wins the thread though ...

Did that bridesmaid have bad social anxiety, OP? The behaviour does make me wonder. Weddings, particularly being part of the main bridal party, are the worst for bringing that out.

🙄

Sparklybutold · 08/02/2026 22:36

My dad - got out of the wedding car to piss behind some trees, left the wedding during the meal, failed to pay the bar bill (he promised)… the list goes on really, but he broke my heart that day.

Dollymylove · 08/02/2026 22:38

These are my favourite kind of thread. Some of them are insane 🤣
I vote the knob in a bread roll the far and away winner 🤣🤣🤣

EsmaCannonball · 08/02/2026 22:43

The groom and best man having to search the local pubs to locate the priest.

The priest refusing to let the best man be the best man because he wasn't a Catholic.

A guest (a teacher, no less) being so leglessly drunk she was falling down before the reception had even started.

YorkshirePuddingsGreatestFan · 08/02/2026 22:48

The parents had split up and were with other partners.

Father of the bride was on the top table with his new partner and mother of the bride was towards the back on a regular table with her new partner.

In his speech, father of the bride talked lovingly about his new partner and how wonderful she was, what a great father he had been to the bride and then made barbed comments about "the other family" referring to the mother of the bride.

Everyone in the room was just cringing.

A bride who expected everyone to set up her wedding the night before (I am tenuously related!), provide food, take turns washing dishes and take down everything the day after! I wouldn’t mind helping a close friend or relatives, but this was kind of embarrassing!

Piknik · 08/02/2026 22:50

Family wedding - Church and beautiful elegant venue. Our lovely, sensible cousin (in his 40s) arrived with his unhinged, self-absorbed financé (30s) that we'd all quietly had doubts about. She turned up in a dress so short you could genuinely see her thong, she was paralytic within two hours, flirting with every single male she encountered, and loudly demanding people feel her 'new tits' by 5pm. She kept trying to do 'sexy dancing' during bride and groom first dance and had to pulled back several times and eventually started talking loudly about lovely cousin and his 'poor performances' in the bedroom.

To shut her up, another older family member told her to 'pull herself together, to stop embarrassing 'Tom' and stop embarrassing yourself'. We all hoped that would be the end of it but she started shouting "Well what have I got to be embarrassed about? Come on then? What?". Family member (now livid) said "well your knickers are showing for one" at which point she dragged them down her legs, chucked them into a small crowd of people and yelled "well you can't see them now, can you?"

Cousin called a taxi, put her in, told her she could keep the engagement ring but to never call him or attempt to speak to him again". And that was the end of her.

We still talk about her in whispered horror.

Not so much a wedding, but have seen a daughter dancing on the table at her own mums funeral

Friend of the groom whipped his penis out, put it in a bread roll, buttered it and went round the tables offering it to old ladies.

You win the thread!

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!

I have an uncomfortable feeling that might have been me

Fgfgfg · 08/02/2026 22:57

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.

I would have said yes please before dousing it in Tabasco

And absolutely no-one had a word with him? I find this hard to believe…

Oh god was it in SE London? My friend did this. Everyone had to help or contribute something, it was really weird and uncomfortable. The whole evening before was spent setting up and it was near Halloween so half of the stuff was leftover decorations. Some of the food was in Tupperware pots where guests had provided it 😭
