Yeah, living close to Philly and going to school down there has taught me a lot of things, usually it doesn't matter how many people there are because someone is carrying unfortunately. I used to be a fighter and can handle my own but it's not worth it usually. I also hear Tiny's point, I'm 6'7 and can be intimidating when I need to
I've never been in a situation where someone has grabbed my girls ass though, I'm sure it's happened but not to where I've seen or heard about it. I also go out drinking with a group of friends so I don't worry about the drunk group. Closest I've come was when I took a girl to Kat-man-du and at the end of the night this black guy started flirting aggressively with her, I played it cool and was joking around with him then she left with me.
It takes a real jackass would start a brawl for someone flirting with a girl.
