Teenage Mutant Ninja Nigga 

A person (specifically Black, but can be Hispanic, or Asian) that knows martial arts of some kind and is between the ages of 13-19. He also has to be someone who usually is: clever, quick,(not literately a "Mutant")has done some "off-tha-wall" shit, somewhat secretive, chills in dark urban areas,(such as a back alley or in the depths of the ghetto) and basically, a bad ass, yet a cool enough person to hang with.

That dude just drop-kicked that cop in tha faze while taking the gun from hiz holster, turned and elbowed one cop that ran up, THEN ducked-n-rolled under tha last cop's leg, shot him and FRONT FLIPPED over tha squad car and dashed 2 his hideout with tha money!
---That's ninja nigga shit!---
