A generic insulting noun, coined by Butt-
Head of MTV's Beavis and Butt-
Head who also gave us words like, "fartknocker", "buttknocker", "Cornholio", "TP", "bunghole" (the
asshole, not a hole in a keg), etc
{Beavis}: What was that,
Butt-
Head?
{Butt-
Head}: Oh just some bungknocker on TV, twirling these big dumb sticks, lighting them, twirling them again, and like setting himself on fire or something.
