A name for a hillbilly, particularly ones from mountain country. Examples include Clem, Bocephus, and Zeke. Female Appalachian Appellations include Daisy & Ellie Mae. Of course, hillbillies do not use the term themselves, since they can't pronounce the word APPELLATION.
"Hi, I'm Bocephus Billy-Bob Burgundy."
"What kind of name of Bocephus?"
"Why, that thar's a Appalachian Appellation."
