There are an uncountable number of YouTube Videos dedicated to this stupid game.  The game is pretty straight forward.  Two people get 30 seconds to just go at each other and fight it out, usually with a crowd watching.  The fight is then posted to the interney (usually YouTube).  It is a way for kids to share their “toughness” or “victories” with others.  Both boys and girls play this game the dangers are obvious.
