This thread is full of guys who are "that creeper" and don't even know it.
Don't act like its an overreaction to be protective of your wife in this (or any) situation, or act like its the wife's job to handle it. Women usually want to avoid confrontation, it's the man's job to take up the slack.
Girls get drugged nightly at bars everywhere, the male of our species is predatory and desperate.
I think a lot of these white knights or soft batch "men" in this thread don't live in the real world.
Or maybe I'm a bouncer in the real world and dickheads throwing punches over the silliest shit ruins an otherwise chill night EVERY. DAMN. TIME. And then they act surprised when they get thrown out. EVERY. DAMN. TIME.
A guy trying to dance with a woman is not uncommon. A guy trying to dance with a woman who is in a circle of friends (guy or girl)? Still not uncommon. I've had guys try to step in front of girls who wanted to dance with me (One girl went so far as to comment that her possessive guy friend was "probably gay"), just because they
assumed that's what the girl wanted.
A guy talking to an attractive woman with minimal body contact is not a crime. If there is inappropriate touching or groping, she can tell the guy to fuck off, slap him, or tell a bouncer or her bf/husband. In that scenario, the guy is totally justified in getting his ass kicked.
Here you have a scenario where there is just a guy doing what he's probably done 1000 times at bars and clubs (you know, chatting with girls and dancing), and the OP acted like a confrontational prick by eyeballing him and grabbing him instead of just calmly saying "she's my wife."
When one of my female friends get hit on, I let the guy say his bit. If she likes him, she'll keep on talking and that's their business. If she thinks he's a creeper, she'll move away or pretend that she's with me. It's that easy. Guys aren't completely retarded. If it's my gf, I
still let the guy say his bit, and I let her turn him down. She's a grown woman, she speaks English, she can easily make it clear that she's uninterested in someone without me having to beat him half to death.
