Spit Knuckle

Eye contact is essential! Spit on the knuckles of each hand, take the clitoris in between the knuckles and slide both of the knuckles up and down gently but firmly.

Lady: Will you Spit Knuckle me, please?
Me: I thought you'd never ask!

Knuckle Fuck

When hitting a large jump (booter) mainly on skis there is a roller or knuckle that the jump sits on. If you hit that jump and land a little short that is called a case. But if you case the jump so hard that you are ejected from your skis and you thrust your body so hard against the landing that is called a Knuckle Fuck because you are fucking the knuckle.

Dude, that guy hit the pro jump line and knuckle fucked the last jump.
