Fuck knuckles

Fuck knuckles are when a teenage boy has been masterbating and constantly has jizz on his knuckles

I will never shake hands with my nephew Johnny because he constantly has fuck knuckles and seems to be always jacking off.

coke-knuckle

when someone snorts all of your cocaine, you get pissed off and punch them in the face. resulting in the cocaine residue getting on your knuckles

Lindsay Lohan snorted all my coke. I proceeded to punch her, therefore resulting in me having coke-knuckles for the rest of the night.

Moose knuckles

A much larger version of the camel toe. Typically seen when a fat woman or a slightly heavier woman wears tight jeans and the saggy area around her vagina forms what looks to be camel-balls.

Damn! Girl could have looked in the mirror before she walked out the door looking like that! If I had known better, she was packing a set of balls, cause that moose knuckles she was sportin' was huge!
