theres a guy at college who is so pervy it makes me sick. he constantly spanks my girlfriend as he walks past, or tries to undo her bra etc. but she just thinks its a joke and isnt really bothered by it. me on the other hand, i cant stand it and it really [censored] me off.

well today he decided to spit a mouthful of water at her (he said in a jokey way), and to make it worse everyone just laughed as if it was something funny. this guy is really beginning to bug me now, and i really want to beat the crap outta him to be honest. but i know you guys are going to say thats not what i should be doing. so my question is, what do i do?

That's not what you should be doing.

... What? You knew I was going to say that.

There's nothing we can tell you over the net that will help you get better at fighting, keyboard commando. But, even if I could, I wouldn't.

You may get some better responses from other people but honestly, grow up.

Oh and tell the bugger to grow up too. If he's molesting your girlfriend and she doesn't mind, well, you might want to have a chat with her about how it makes you uncomfortable and you think she's encouraging him.

Leo is absolutely correct, tell your girlfriend that you're uncomfortable with this guy's behavior, and ask that she not encourage him. If what you say is true, IMHO, this person is engaging in an adolescent flirtation with your girlfriend, and trying to pass it off as humor. That way, if he gets shot down, he can always protect his ego by saying he was just joking around. But, he'd go for it if he gets enough encouragement. This is something more commonly seen in Jr. High; he sounds really immature for a college student. Anyway, it's perfectly OK for you to politely but firmly demand that the guy cease and desist. Personally, if anyone, friend or not, tried to spank my wife, or unhook her bra, I'd be in their face like ugly on an ape, demanding an apology. (However, if your girlfriend says that she doesn't mind this treatment, I'd think twice about your girlfriend.)

Sounds like someone needs a serious "wedgy"... in "jest", of course.

This is college?!? Let's see - spanking, water spitting, melodramatic anger...
are you all in clown college perhaps?

You don't have to beat him up... at least not physically.

Psychological warfare is far more effective.
Next time he spanks your girlfriend's rear, start gently rubbing his. Invite him on a camping trip so you can "get to know each other better". Gaze dreamily into his eyes.

This could, of course, backfire dramatically.

Maybe start rubbing hers with cream to sooth it after he spanks it... errm, that's a bit off-thread!

Wow, and I wonder why Victor Smith resigned from this section...
