Pink Knuckle 

A ragingly, engorged clitoris.

She was so horny her pink knuckle was all swole up.

I was stroking Rachel’s pink knuckle last night. She was squirming and squirting.

Ukrainian knuckle duster 

A sex position in which you double fist a woman with your wrists together, while squatting over her and slamming your hands inside the woman's cooch like an oil well.

Sex isn't the same with my wife anymore since she let me whip out the Ukrainian knuckle duster

Pee Knuckle 

A game where you and a friend sit on the ground across from eachother, with your feet touching. The first to kick the other in the balls first wins.

Me and my brother played Pee Knuckle when I was 7, I'm starting to think that's why I can't have kids now..

graveyard for knuckle children 

Nickname given to the bedroom of a male in his mid-20s who still lives with his parents and is hopelessly single, ergo, masturbates frequently. There is an audible crunching sound upon entry, reminiscent of the scene in "Indiana Jones and the Temple of Doom" when Indy and his Lady Friend discover a secret passageway and proceed to walk through it in darkness to the sound of insects being unknowingly crushed beneath their feet.

Scene: Dustin's room, aka "graveyard for knuckle children" - When the police turned on the black light it was clear that this was ground zero; for after all, it was a graveyard for knuckle children.
