What would you do?

Well, I've got this violent vietnamese after my head because I told him he had serious problems when I kinda flirted a little with his girlfriend and he told her not to talk to me.. Is it a good idea to say "I'm sorry" or should I provoke him a little? I really want to provoke him, but I don't think I can kick his ass, and I don't know who's got the most friends of us.. So, what would you do?
