I've sort of tried "The Opposite." Most of the people in my fraternity see me as a pretty quiet person who really only talks when he has too- i.e. I don't like to hear myself talk. A week ago I got a pair, and blew up at one of the brothers. Since then, I've been just tossing out insults at anybody and anybody, while still remaining cool, calm, collected, and friendly. My brothers respect me much more and actually *like* to see me loud and obnoxious, though they *know* that's not how I REALLY am. Try it, but be careful with it. It'll really throw people for a loop.
