Fudge-knuckler

Common terminology for one who engages regularly in the act of fisting. May be used descriptively, or abusively at your own discretion. It is generally frowned upon, if assumed as a title.

Cad-flangin' dangle-hoppler! That sombanitch Carl is a damn fudge-knuckler! I figured him straight and narrow, but I guess he likes to play out back.
