You train MMA. That's cool. It's a good sport, lot of fun, great exercise, etc. and it's good for self defense and competition.
Self defense. That's when you are physically attacked and your safety is in danger. Not when somebody calls you a bitch. "But yeah dude, but he was talkin shit bro!" Tough. Deal with it. It happens. Responsible adults don't get into fights over name-calling, and if you aren't a responsible adult, this isn't the sport for you.
Competition. That's when two willing, trained athletes compete under the direction and supervision of coaches, referees, and other licensed officials. Not when "check it bro he heard I took UFC classes so we fought after the basketball game." You're not proving anything by having sloppy fights with people who don't train, and if you're losing them...God help you.
Anyway, don't mean to gripe, but I'm about to have a "come to Jesus meeting" with some of the high school meatheads in my class, figured I'd post a little reminder here. Most of the posters here seem pretty level headed, but you never know who's lurking..
