hovering knuckle 

An alcoholized drink that hits the drinker by surprise shortly thereafter. (i.e. the image of a hovering fist suddenly clobbering the drinker)

Man, that tequila shot was a total hovering knuckle!

tummy knuckle 

the very center of a persons' abs (more common when it's a 4 pack) that is harder than the rest of that abs, and tightens similar to a knuckle. It hurts when hit directly, similar to the pain of playing bloody knuckles.

(out of stupidity) I'm going to break your tummy knuckle!

My tummy knuckle hurts after doing so many crunches.

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.
