The tendency for a normally smart and well-adjusted black American to suddenly and inexplicably become hostile or incapable of rational thought. Often happens during puberty or during their late teens/early 20's. Once afflicted, the symptoms tend to be irreversible. Symptoms include becoming hyper religious, falling for black nationalist rhetoric, becoming physically violent, throwing away close friendships with anyone who isn't dumb and ignorant, and generally giving black Americans as a whole a bad name.

Kai: You serious? Bro, what is up with all these cases of nigger brain? Is it an actual disease or something?
