gotta go with the general consensus here and say fight club. There was a year or so when I was 17 that I wanted to be tyler durdan.

Inevitably, myself and a group of friends started our own fight club. Surprisingly, we actually had some good fights, no one got seriously injured, and it lasted a couple months. We had three rules.

Rule number 1: You do not talk about fight club
Rule number 2: YOU DO NOT TALK ABOUT FIGHT CLUB
Rule number 3: No punching in the face or balls and must stop as soon as someone taps out or yells stop.

Actually we just had the third rule. I miss those days.
