Knuckling 

The act of stimulating the clitoris by vigorously rubbing ones knuckles back and forth in a sawing motion.

Will walks in on Kraig and Felicity in bed together , and Kraig is violently rubbing his knuckles on her pussy.
Will: What the fuck are you doing to her ?
Kraig: I'm knuckling her! I'm getting her inflamed!
Will: Dude, just fuck her already...
Felicity: He won't fuck me until I officially go out with him.
Will facepalms, and pukes a little in his mouth.

knuckles 

A game where a group of people sit around a table with a coin, preferably £1, but most/any will work. One player spins it for the person on their left to catch between their index and middle fingers. Play moves in a clockwise direction. If the spinner mis-spins it 3 times, the catcher slides it along the table very quickly at their knuckles. This also happens if the catcher catches it with the coin horizontal. This happens in reverse if the catcher mis-catches it (once).

We played knuckles in school today, and people were wondering why our knuckles were all mashed up.

Knuckles In 

A sexual position in which the man's fists are turned inwards and placed on either side of the females neck, to prevent her from moving away due to thrust. See "Gorilla Style."

After a bottle of Jameson, the only way to get it done is by going knuckles in!
