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. :)

i'm going to Mewtons Knuckle you so hard your taste buds will never work the same.

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.

knuckle scrub

The act of vigorously scrubbing one's anus, usually with hot soapy water, to clean it of leftover fecal matter. It is more a practical technique than a pleasurable one, although some people find it serves the dual purpose.

The toilet paper at the resort was of poor quality so I had to hop in the shower and do a quick knuckle scrub before going to dinner.

Knuckle Symphony

1. The sound you hear after being punched repeatedly. This is usually accomplished by a bully of some sort.
2. The sound of a habitual knuckle-cracker, especially one who is capable of cracking many knuckles at once.

"Oh man, Jimmy's probably hearing a knuckle symphony right now! Lets call an ambulance."

"Hey, man, thanks for the knuckle symphony right there. Really appreciate it."

To masturbate. Jack off. Rub one out.
