A person, often inbred, who engages in hillbilly-ish activities such as porking the pooch, screwing close family relatives (incest), feeding and eating pigs, spitting in a tin can, and playing the "banjo." Often racist towards black peoples, calling them hateful names such as nigger, coon, niglet, negro, etc., and often embarking on coon hunts.

Not to be confused with Chuck Norris or Beverly Hillbillies. Often frequents trailer parks and small country bayous.
