This is going to be a very simple fanpost (you are all thanking god right now). And yes, it has been done many, many times before.
I have always been fascinated by fighter's nicknames. Some capture the essence of a fighter and their style ("The Spider" "Mayhem" "Rampage" "The American Psycho" "Hendo" etc.). Some don't do so well ("The Terra" "Twinkle Toes" "J-Lau" "The Cat Smasher"). So my questions for all of you are, what is the best nickname in MMA, and what would your nickname be if you where a fighter?
