A nigga with a massive chin. Often the alpha male. If one runs into another Nigga Chin, they will battle for territory and chics by jousting with their massive black chins. If you drop soap in a ten mile radius of them, they will teleport behind you and tape you with their chin. Not to be confused with the geto version of the nigga chin, for he is not a wild untamed beast of Africa.

A chin that is bigger then ones penis.

Nigga chin is a chin with the same energy as Pickle Chin, but nigga.
