A person is a comedy bitch if they are used by their peers for their own amusement irrespective of the shame and embarassment it may cause the bitch. However, the bitch in question must be a willing party.
A phrase which despite its possible connotations is not in any way sexual.
It derives from the incredibly amusing activity of beating your rival's oversized burger in the Fuzion Frenzy mini game. This is a race, the result of which both the competitor's future pride and dignity is decided. FOR EVER.
The action on screen must be accompanied by some hard-hitting anthems (ie. Smack My Bitch Up, Bombtrack etc).
