When you get fisted and shit comes out onto the hand
I once shart-knuckled a girl and her asshole exploded violently.
Mens underwear, skivvies, tighty whities, boxers or briefs.
"You can't buy a knuckle Basket like that at BB&B"
A ball sack that looks like a chicks camel toe.
Damn that's hot look at his knuckle bag, I wouldn't mind slapping that around ever once and awhile.
When a gay man, or woman/ straight man, or woman shoves their hand up there partners ass then pulls out there shit then chucks it at the wall, or in there partners face
Hey girl wanna do the monkey knuckle
A fast knuckle. A knuckle that goes exceptionally fast.
My speedy knuckle goes faster than the rest of my knuckles
Moose knuckle or camel toe, but in the back. As if someone was wearing spandex and hiding two bagels between their legs just under the grundle.
“Oh man, this woman flossed a wicked mass knuckle yesterday at the swap meet.”
