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?

Oh…another classy affair!

Well she dealt with the issue rather than everyone smiling through gritted teeth as the vows were ruined. So I say Go Aunt Sadie!

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.

Omg that can’t be true 😂😂😂😂. I am crying at this!

Probably only me that had to look it up.

A croquembouche (French: [kʁɔ.kɑ̃.buʃ]) or croque-en-bouche is a Frenchdessert consisting of choux pastry puffs piled into a cone and bound with threads of caramel. In Italy and France, it is often served at weddings, baptisms and First Communions.

I had to google how to spell it 😂

Jesus, we are in the process of setting up a unique wedding venue, restored building for the venue and a fair amount of accommodation on our land and this thread has me panicking.
Wonder would I get away with an alcohol free venue?????😂

I wouldn’t rely on that.

Our wedding was alcohol free (my dad and groom’s dad were alcoholics - my dad dry drunk, my FIL died of liver disease) and it was clearly specified on the invitation because we just did not want any drama from all the other big drinkers in the family.

When I say “specified” I mean not about the alcoholism but about it being soft drinks only.

STILL people snuck in bottles of wine / liquor - one my dad’s golf buddies got so drunk from his smuggled in wine that he vomited under the table. He would have been in his mid to late 50s at the time. Ridiculous behaviour. 🙄.

This thread has made me realise that there was some really shitty behaviour at my wedding that I clearly blocked out!

When I was a student in Edinburgh, a friend's-friend started a business as a wedding photographer. He got a gig in a fancy hotel near where we lived and invited us along as his 'assistants' ie free food and booze in exchange for carrying some bags for him. It was a big wedding, loads of champagne flowing freely. The first dance had finished and lots of guests were up on the dance floor. Then some bloke (one of the bride's brothers apparently) came charging across the room, launched himself at another man, they both flew backwards and crashed right through a set of french doors onto the terrace 😱where they proceeded to kick the shit out of each other. Half the dance floor followed them outside (it was summer so still light) and either joined in or cheered them on. Fucking mental. The bride was inside bawling her eyes out and being comforted by her mum and bridesmaids. My friend and I stayed in the (free) bar with eyes on stalks while the photographer carefully packed away all his expensive gear in the middle of this total barney.

Bride's brother - spend the whole event drunk and obnoxious and was completely vile to his wife. His mum kept asking the wife to tell him behave himself, like it was her responsibility. After lurching round the reception upsetting everyone he attacked the croquembouche with the ceremonial sword. It was all very awkward. I can only assume he was either mad at his wife or his sister or perhaps both as he made absolutely sure neither of them would have any happy memories of that day.

Am I the only one who thinks the penis in the bun guy should be locked up? Sicko !!

Nope I agree , it’s indecent exposure.

That is horrible. What happened afterwards?

Credit to the photographer. Some would have just quietly deleted the photos.

> What happened afterwards?

She called the police from the photographer's studio, the photographer advised her to go two doors down to a solicitor and start divorce proceedings

He did a lot of awful things during the divorce, including killing the family dogs and leaving them in the back of her car, but in the end he got ... five? ... years, and the house was sold and she took her half and moved away

Uricon2 · 10/02/2026 11:29

I obviously wasn't at this one, but sometime in the 1880's, my great grandparents. She was 15 and very heavily pregnant, he was so drunk he repeatedly fell on the altar steps. The vicar paused the ceremony to say that gt grandfather was a disgrace, his new wife was a credit to him and he was only going ahead with the service because he felt sorry for her.

The marriage didn't get any better, sadly. Proof I suppose that bad behaviour at weddings is nothing new.

I have attended quite a few weddings over the decaded. Most went well with only a minor hitch or two. I have never witnessed any of the behaviour like the stuff I have read on this thread, I feel a bit cheated tbh 🤣🤣🤣

I feel exactly the same way, totally cheated, I want to be at such a wedding before I pop my clogs and I'm seriously old! I can bring the very hot chilli sauce for the filled bread roll and a long fork.

Didn't see, but was told about it.

The groom wasn't able to get into the bathroom because the bride's male family members occupied it for 4 hours with showers, shaves, hair, everything so that they looked good and laughing that they weren't going to let him in.

When he finally got in with 20 minutes to spare, they turned the water off at the stopcock and shouted through the door that if he didn't come out right now, they were going to tell his fiancee that he'd changed his mind after being caught with a stripper on his stag (which he hadn't gone to because they'd told him he was going to be handcuffed naked to a lamp post).

He panicked, came out, his suit was missing from his room, nearly burst into tears, then had his suit thrown at him in a bin bag - and had to get dressed still unwashed & in a creased suit because his fiancee's biggest uncle had turned up to collect him and was hammering on the door to get a move on, as he was keeping everybody waiting.

The marriage didn't last.

Lucky man to escape from such odious in-laws!

I forgot the one where the grooms parents left because of the best man's speech (it was close to the wire but not that bad).

Or the lesbian one where an uncle did a speech and said "you both look so good, I'd shag you both". Awkward.

Loooove the uncle speech.🤣🤣🤣🤣🤣🤣

TotallyAddictedToCoffee · 10/02/2026 10:49

My no longer a friend got obnoxiously drunk and spent the whole evening making a fool of herself

We had those centre pieces that were a giant martini glass filled with those little jelly balls (like orbies) with floating candles in them - she proceeded to fling them at people, including my elderly grandad....

She lost her leg in an accident when she was 17 (she was about 40 at the time of my wedding), and she spent the whole night telling everyone that she "learnt to walk again to this song" to every other song that the DJ played!

She encouraged her daughter (12) to be snidey and mean to my DSD (11) who was our bridesmaid, leaving DSD out and running away from her - it was really childish and pathetic

She came across as really jealous and I haven't spoken to her since - it's been 14 years

HectorPlasm · 10/02/2026 09:49

Forgot something from my wedding - the reception venue had floors at different levels so often up one step or down one step as you moved about. This wreaked havoc amongst the elderly guests and later the drunk ones - they were going down like nine pins. It was like the beach scene from Saving Private Ryan but without the sea, sand and gunshots!

Oh dear
Snorts 😂😂😂😂

CherryRipe1 · 10/02/2026 10:34

Traveller wedding, massive drunken fight at the reception that spilled out onto the carpark. It wouldn't be a Traveller wedding without a massive brawl I was informed.

Friends daughter's wedding at a very posh venue in Henley, mother of the groom got paralytic & was carted off to her hotel room to sober up.

Ex husbands auntie had a massive drunken row with her husband, the groom at the reception in a pub. Picked up the cake knife and threw it at him like in a carnival or circus act, with such force it narrowly missed him & stuck in a wooden support by the bar. They divorced a few months later.

CruCru · 10/02/2026 10:33

I’m a bit taken aback at all the weddings where people have taken drugs. I can understand getting drunk but taking drugs at a wedding is just a bit weird.

Of all the people I have told this story not one thought it was acceptable to storm into a church during a wedding screaming - regardless of any inconvenience. I just remembered why I avoid posting anything on any forum.

Really? I think you behaved very badly.

Got to be the one where we left the reception and there was a fight in the car park. As we drove past we noticed it was the bride and groom fist fighting. Friends of dh not mine 😅

Stoppp 😂

Just reminded me of one we went to, a marquee affair so no specific end time, and this was around 3am. It had been a great party but really everyone was getting very worse for wear and needed their beds. The normally absolutely lovely, mild-mannered groom swung for his new-wife’s sisters boyfriend, who in turn shoved over said sister in order to return punches. We felt it was a good job well done as we managed to hustle the groom outside, he wasn’t a small bloke, only to bump right into his cousin who, probably 10 years before and before the groom and his bride were officially together, had a very minor fling with said bride. It was like throwing a match into a box of fireworks, I swear every member of the family got involved, it was horrendous! We beat a hasty retreat. Apparently the groom didn’t make it to bed, he slept on the floor in the porch of their new marital home! They’re still happily married and that side of his character has never ever been seen again… most bizarre!
