The opposite of the White Man's Overbite.
The goofy smile on a nigger's face when he is dancing at a club with an overweight white bitch.
Onlooking negro #1 "Hey, check out Tyrone on the dance floor!"
Onlooking negro #2 "Playa's Nigger Grin is makin' all those white craka's go crazy!"
Onlooking negro #1 "Wanna go steal a TV?"
The face a black man makes when he is about to steal your wallet.
Katherine! Run! The black man gave you a nigger grin.
