I also have a friend who is a master at wing chun kung fu. Another aggressive (perhaps too aggressive?) style that trains you to disable people in a heartbeat. It also helps that he looks like a black Terminator and won't back down from anyone or anything. Literally, he has had most of his opponents completely psyched out before the fight starts (I know, I was there when he challenged 6 guys outside a club and they balked).
