When a black American person is so ridiculously afraid of a benign object or event (i.e. a boa constrictor or David Blaine's Street Magic) that they scream at the top of their lungs while proceeding to run amok in public.
Man, I was in jail, and every motherfucker beat my ass cause I was honky, or a nigger, or a spic. They didn't know I was a jiggaspacker. Then I thought about makin' my own jiggaspackin' gang, but there aren't any, YET!!!
