Knuckling one off 

When an fat dumpy lesbian beats herself off and since she's so fat she aggressively rubs her knuckles on her puss to get off

Patti couldn't get the job done with her dildo so she ended up knuckling one off on that big fat pussy

white knuckling 

When you're taking a situation as it comes and flying by the seat of your pants. Often attributed to anxiety, and feelings either good or bad. A reference to clinging fiercely to something, such as a rope, to the point where ones knuckles would turn white from forcing blood from the capillaries.

Jesus, I'm sweating, I was white knuckling my way through that interview. Those guys are scary.

Knucklin 

A more aggressive version of fisting that results in g-spot or prostate contusions.

"Yo, bra, why's your hand in a cast?"
"I broke it knucklin' your mom last night."

-or-

"Why are you walking so messed up, were you riding a horse?"
"Naw man, I spent last night getting knuckled by 8 dudes and now my ass is broken like Angel's face from Fight Club."

Cum Knuckling 

Barbaric way to impregnate a woman. The correct method would involve firstly restraining a woman. Next a male will proceed to orgasm onto his fist where he will punch the female in the vagina. Repeat with fresh cum every 2-3 hits to insure efficiency on this most delicate of procedures.

This valentine's day my wife and I will be cum knuckling our night away after I take her out for a nice seafood dinner.

-or-

I was about to cum knuckle you babe, why do you look so sad?

Cum knuckled is the correct past-tense.
