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 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 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.
