mewtons knuckle

When you're wearing a thong, and your balls are so saggy that each ball falls onto both sides of the thong creating newton ball like balls, and you have someone put their tongue in between both balls, and swing the balls together like newton balls. :)

My neighbor is a real jack knuckles. He’s always giving himself a wank online.

My uncle is a jack knuckles. I catch him tossing off every time I walk past the den.

Fuck that guy. He’s a jack knuckles.

Burnt Knuckle

An extremely sore clitoris. Usually from too much bean flicking, relentless railing or aggressive oral.

Well with all the lockdowns I’ll be alone over thanksgiving watching porn and flicking the bean. I’m sure come Sunday I’ll have one burnt Knuckle.

That old butch lesbian sure can munch a box. She worked my slit for hours and left me with a sloppy burnt knuckle.

My little love box was unable to take his meat so the relentless pounding left me with a burnt knuckle.

Monkey Knuckle

When fisting someone's anus, and you pull your fist out covered in poop.

I can't believe they didn't clean themselves enough to prevent me from getting monkey knuckles.

3-way knuck

When you and 2 of your buddies celebrate a good game of darts, and you do a “3-way knuck”. A fist bump between 3. A rare simultaneous connection of knuckles felt between each individual.

After our game of countdown, we did a 3-way knuck to celebrate the game.
