My partner was "bullying" his 17 year old coworkers boyfriend "for fun" it's freaked me out beyond belief

Not 'weird' it's nasty.

Your boyfriend is an incredibly nasty man.

He wouldn't be my boyfriend after all this. How long before he turns his unpleasant nasty behaviours on the people you love?

Straight in the bin 🗑️ with him

He’s only worked there since September but thought it was appropriate to behave like that? What a complete TOOL - don’t be a drunk arsehole at a work event.

This is so wrong!! How could grown men treat a young lad like that and think it’s ok? It sounds way past banter! I have an 18yr old DS, he’s a little socially awkward and shy, it would really upset him and intimidate him if grown men were behaving like this with him.

God, that’s awful. Agree that he fancies the 17 year old and this was his weird way of showing off/trying to assert power. Like that horrible whatshisname from Masterchef. Of course, the 17 year old will think he’s an absolute dick.

Disgusting behaviour. Also, it’s a work event so expect him to be disciplined if she makes a complaint.
I couldnt be with someone who is a cruel bully.

Don't have kids with this man.

Sorry OP, I’d also assume he either fancies the 17 year old girl, or something about this boy made your DP decide he was weak enough to bully without fear of being turned on.

but the former is more likely.

if you don’t have dcs then id be ending this. He might not have shown this side of him before but it was always there and why this boy triggered it is a worry.

Do you really want this lemon in your life OP?

I would be blocking and walking away today. There is nothing you can do about a person with a nasty mind and zero empathy for others. It just is that way. He will be the same when he is an old man.

I’d say he fancies her for sure. What disgusting behaviour, it would change my opinion of him.

I don't think I've ever heard a bully actually come out and admit/realise that their behaviour is bullying - much less proudly boast about it.

Not even behaviour that somebody might (wrongly) try to brush off as 'just a bit of teasing' but horrible, gratuitous nastiness and deliberately negging.

I can't even work out what the asterisked insult is meant to be - all I can think of is a variation on a disgusting old racist term.

He sounds absolutely vile - I presume he's an ex now? As PP have said, at least he's done you the 'favour' of showing you who he really is.

That was my first thought. He fancies her and has a very nasty streak. Hopefully, as Christmas do's are work events, she'll complain and he'll get sacked. He deserves it.

What a nasty piece of work!
Red flags all over the place.
Who on earth would even do that to an 18 year old stranger?
If that's what he calls entertainment, you should walk away quickly in the other direction OP.
For Christmas, I'd give him the gift of being single.
YANBU.
He's just a big fat NO all round.

Very nasty also dull and humourless. He sounds boring as fuck and as thick as mince.

It all sounds a bit "lads, lads, lads" on some tradie work do. Either they are all protective of this young girl and have taken this too far or there's something weird going on.

It doesn't sound very nice so I'd be having a chat with him. Was he drinking? And taking drugs? It all sounds like a poster for toxic masculinity.

What the hell! Ltb

really upsetting reading this as a mum of three young adult boys. Bloody awful . I’d be murderous if my son was treated this way . You are right to be feting how you do . No way could I be with this disgusting specimen

I would leave him. I would. I could never be with a man who bullies people, especially teenagers. You just know he was a school bully. And has not grown out of it. Is that the type of man you want to have children with? You know if your and his children are ever bullied he will tell them 'its a joke', 'toughen up', 'get over it'. He would not have their back. He has shown he is a horrible, nasty person. When he shows you his true colours, believe him. I could not come back from this. Ever.

That was my first thought, that he's jealous of the boyfriend because he fancies the 17 year old.
His behaviour was childish and immature. I wonder if he's a bit of a bully in general at work and that's why others joined in.
How long have you been together?

^^

This. My first thought was he's a bully who's doing some weird male dominance display, to impress a 17 year old girl. The sexualised and shaming comments re her getting 'railed' are a huge and disgusting red flag 🚩🚩🚩
Sorry OP but your partner sounds creepy, misogynistic and also a bully!

Well that is horrible behaviour.

He really must fancy this young teenager.

And he obviously has friends who think this is a normal way to behave.

Is this the normal culture of his work place because you would hope he should receive disciplinary procedure for this?

He has shown his true self and it would make me question the relationship.

Because this happened at a work night out I wouldn’t be surprised if someone reports all this to HR. Your boyfriend will be lucky not to be sacked.
Just break up with him.

YANBU OP

That behaviour is absolutely shit

I'd be shocked and ashamed too.

Whatever else he is, your partner is not a decent man, and that part of him can turn on you when it suits him and he thinks you are vulnerable. I'd get rid now, before that happens.

What a horrible thing to do!

That’s not normal at all. Why on earth did he tell you he behaved that way? Did he really think you’d be impressed? I’d be getting the ick right now so badly that I’m not sure it could ever be reversed.

and saying aw your girlfriends definitely getting railed by so many men right now, to "make him insecure".

^ Particularly stands out for the revolting misogyny.
