hillbilly

Apocryphal attribution to isolated denizens of Appalachian Mountains,(Eastern USA) descendants of some of the earliest Scotch-English settlers, who seem to have had some proclivity for naming their children "William" (familiarly "Bill")and some not inconsiderable inclination to incestuous sexual congress. More recently, the term is used to describe any rural resident,especially in the Southern USA and particularly those living in rather rough-hewn conditions, embracing noticably parochial ideologies and a generally hostile attitude.
