That's a a bad game to play, bro.  I agree, it's fun to think about giving some douche what's coming to him, but the fact is 1: His friends will continue the fight against you and your friends if you're lucky enough to have them with you, and 2: Legally you're a coin flip away from an assault charge that will always be on your record, along with the fines and lawyer fees that come with it.  No good can come from it.
