This term is used to describe the mating habits of the people that inhabit the Appalacion or Ozark Mountains.(Also has been seen to happen in Rio Linda and Arbuckle, California.)This is the only true way to become a full blooded hillbilly.
Those hillbillies are so In-Bred that the son of the father's daughter is also the half-brother of the father.

This usually happens because they are so ugly the only other people that will have sex with them is members of their family. Easily noticable by lack of teeth, looking like they have been hit by a train, or bad english.
