foot knuckle

The bony protrusion on either side of the ankle.

Oh man, during that slow pitch softball game my foot knuckle got tore up by a low ball!

Foot knuckling 

The art of inserting ones toe up whatever orifice, all the way up to the hilt

Shit me mate......he stuck his toe right up to my tonsils - the dirty low down foot knuckling son of a bitch

Foot Knuckling

The act of stimulating the clitoris by curling one’s foot and vigorously rubbing ones foot knuckle back and forth in a sawing motion.

Will walks in on Kraig and Felicity in bed together , and Kraig is violently rubbing his foot on her pussy.
Will: What the fuck are you doing to her ?
Kraig: I'm foot 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.
