A racial slur, derogatory, for white people in general.
Developed from the annoying habit of most white people to live in the suburbs, avoiding the "undesirables" that live in the cities themselves.
Created because cracker, honkey, cornbread, and other terms for whities just arent offensive enough. Hopefully this does the trick.
You see those ignorant Burb-Niggas at the Celine Dion concert the other night? God damn they have no taste in music...
