A crappy TV show on MTV that was hosted by another crappy actor. This show was about "battling" people (from other neighborhoods) with their stupid jokes about each others moms and other dumb crap to win prizes. MTV thought this show as so cool it made them feel smart.
Also a way to start off a joke.
Guy 1: Yo MOMMA loves Wonka Nerds so much, I told her I was a nerd and she started sucking me!
Guy2: What? What the fuck? I don't get you.
