A fusion of the racial slurs nigger and wop. Used to refer to a black urban gangsta who is obsessed with creating a Mafia-esque public image. Likes to wear pinstripe suits, drink Italian beer, watch the movie "Scarface," and write rap lyrics in which he compares himself favorably to Al Capone and other famous Mafiosa.
Similarly, the term "spicwop" describes a Latin gangta so obsessed.
Damn, you be one lazy nigwop!
I'm doin' it strictly 4 mah nigwops.
