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.

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.

Knuckle Cock

Finger fucking a guy's girl under the table at a bar while he is at the table, then punching him in the face afterwards, karate style, with two fingers, like Chuck Norris.

I knuckle cocked that douchebag and took a shot of Jack to top off the night.

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 Custard

A busted load of jizz all over your fingers after rubbing one out.

Hand me my gak towel. I need to wipe up this knuckle custard.

I apparently didn’t wipe my hands good after jacking off this morning. I still got knuckle custard on them.
