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.
Bill: Yo, you hear what happened to Karmelo?
Kai: I haven't heard from him in years. Dude was always pretty chill and fun to hang out with. What happened?
Bill: He got a bad case of nigger brain. Stabbed a kid at a track meet out of nowhere for no reason.
Kai: You serious? Bro, what is up with all these cases of nigger brain? Is it an actual disease or something?
Bill: Must be. We all know he's not the only young black person to flip their lid and go crazy over nothing out of nowhere.
