Swamp Knuckle 

A hybrid of moose knuckle and swamp crotch that can only be created in the moistet of environments.

When a woman who is sporting a predominant moose knuckle, is sitting and marinating in a humid environment or pours water on herself to cool off, creates a swamp like environment in her nether regions leading to what can only be described as swamp knuckle

the five finger knuckle shuffle on the one-eyed, blue-veined, purple-headed, custard-chucking, salty yogurt slinger

Masturbation.
In other words:
Choking the chicken
Choking the monkey
wacking off
jerking off
shaking hands with man's best friend
teasing the weasel

Dude, we all know that last night you did the five finger knuckle shuffle on the one-eyed, blue-veined, purple-headed, custard-chucking, salty yogurt slinger.

Penis Knuckle 

1. When the penis is folded over in your pants and protrudes through revealing a short nub to be seen by all, giving you that uncomfortable feeling that you cannot fix when you are in public.

2. A lazy person who is dumb founded to everything around him/her.

After the awkward silence, he said, "Why you gotta be a penis knuckle?"

You're a penis knuckle!

twat knuckle 

In the literal sense, something utterly uncomfortable and unnatural--an aberration. In addition, a complete asshole; someone whose presence makes you wish time travel existed so you might jump back to their conception and prevent it. A total cunt.

"You're such a fucking twat knuckle."

"My twat knuckle is really achy today!"

dick knuckle

Similar to penis wrinkle, it is a term used to describe a useless person. Think about it, how useful would it be for a dick to have a knuckle?

Jimmy - "I ate the rest of your chicken."
Buddy - "What a dick knuckle."
