To ban DP’s best friend from my house?

You don’t have to see the friend again. However, you do have to see your DP and you are missing the point that he is obviously just as bad. The friend was using phrases etc that indicate they came from your DP. If your DP doesn’t have the balls to tell him to grow up, and in fact clearly talks about women (and you?) like that when they are alone, do you really want to be with him?

You lie down with dogs don't be surprised you get fleas.
This is your partners friend.
They hang out and clearly talk.
They are both disgusting.
How they view women is vile.
You are only kidding yourself that your partner is something the innocent party.

Scum hanging out with scum.
Really not complicated at all.

But your partner obviously made the comment initially… because his friend had never met this neighbour before yet he was able to reference a neighbour whose arse your partner had remarked on. This friend just didn’t make a random spontaneous comment. You’re entirely missing the point…

So your boyfriend used to "pull" women he thought were unattractive purely to make a mockery of them? Even at Uni age he should know better.
And at some point since you or the neighbour moved in he's found time and made the effort to give his mate a critique of her physical attributes...presumably without the excuse of being uni age.
Think you've had a bit of an eye opener as to his fuller character OP.

My ex had a dickhead friend like this and I also ended up saying he couldn't come round to our place because he was just vile.
He came on to me a couple of times and I told him no, thanks. And then he started saying all kinds of awful stuff about me to ex about how I was old and ugly and that he should split up with me.
Ex was absolutely awful when he went out drinking with dickhead.
And that's one of the many reasons he is an ex.

As someone else upthread has said "Birds of a feather flock together"

Men like that are the WORST.

I'd definitely judge DH a bit for hanging around with such a momentous prick.

I tell you what op, since you don’t believe us, why not ask your darling partner to see his text messages between the two of them.

Vomit inducing.
Yanbu. I would expect your partner say something to him.

you will take no notice of my warning, but if you marry or have children with a man like this, you are setting yourself up to be miserable and exhausted.

@LeonieJDYeah I wouldn’t be too surprised if he ends up on your sofa tonight, regardless op! Particularly if your DP is ‘weak’

I can't believe you're letting your dp off the hook by saying that he's "weak". Not so weak when he described your neighbour's ass, was he? I think he's just twofaced and you saw who he is when you're not around thanks to his friend.

I wouldn’t have this conversation over text, I’d speak to him face to face. Anyway, if your DP is a misogynistic pig then it’ll become self evident sooner or later. He definitely could do with ditching this charmless idiot. My condolences to his fiancée.

The issue is not your DP's behaviour years ago, nor his charmless friend. The inexcusable thing is him referring to your neighbour like that. You only seem to have a problem because you're not confident about your own body!

But he was a misogynist at uni and seemed to treat women like wank tissues it appears

That’s detestable and pathetic.

It almost sounds as if the repulsive friend wants to sabotage your trust in DP. Is he single? Maybe he wants his drinking buddy back on the pull with him.

You need to talk about this seriously with your DP tomorrow when he’s sober. You need to find out if he’s been drooling over the neighbours bum for a start - that’s hideously disrespectful. Plus make it very clear why everything this guy said was unacceptable.

That’s your DP’s best friend….what is it they say about birds of a feather?

This - OP is really focused on the wrong thing but I never cease to be amazed at what some people will overlook to have a man.

Oh my. The rose tinted spectacles of lust are having their work cut out here. Shy? Not assertive? No. Weak. A coward. If you’re not part of the solution, you’re part of the problem.

Where did he get “she’s the fit one with the arse” from….

I would not want you to meet the friend again and it would put me off my partner.

I would give DP the benefit of the doubt.

I cringe at some of the things I said as a young adult. I am not proud of them, and I definitely wouldn't want to be defined by them.

But I would be saying to DP if that is actually who DP is too, then he needs to say now as I wouldn't be happy with him making those comments and it would be a relationship breaker.

DP’s friend tapped him on the shoulder and casually asked ‘is that the fit one with the arse?’ - he has never been to our house before so someone has clearly referenced her.

Er...not someone. Your partner.

Yet he's been salivating over your neighbour and taking to his mates about her arse? I get the impression you're only getting a version of him.
