A fuckabilly is a hillbilly who has lots of sex, usually with relatives.

Get the fuckabilly mug.
A term used to describe attractive or hot red neck guys. It is a play on the words fuck and hillbilly. Although it can be used by heterosexuals, it is most often used as gay slang in the South to describe extremely hot and masculine guys.

An attractive,masculine, young man. Basically a hot redneck guy you want to fuck. The stereotypical fuckabilly is under 30, dresses in typical redneck attire, might have facial stubble, very handsome, and is tanned and toned. Many fuckabilly's are on the "down low" and only like to receive oral pleasure and maintain that they are still 100% heterosexual which adds to their attraction.
