look up any word, like fellated:
 
1.
A breed of tweeker found primarily north of the Carefree Highway. With a distinct lack of morales, genetics, and teeth. Often found wearing a mullet, chaps, and pointy toed boots; any of which have been worn stiff.

Although the Tweekerbilly is domiciled North of the Carefree Highway and more specifically the taint. They have been known to venture South of the Carefree to score or serve time.
Dude that guy is wearing assless chaps and riding a bike - he must be crazy. No man were in Black Canyon City. Up here they call them tweekerbilly and that's your bike!
