Stephan Bonner got his nickname from one of the fighters on TUF. They were just throwing around nicknames for everyone and some one said Bonner looked like a pycho and he has that all american accountant look at the same time thus "The American Psycho". They got it from the movie. Your Welcome Everyone. This was a good thread. Props to Bulletproof.
