Thunder Knuckle

The act of two lesbians forcefully, but lovingly, inserting the knuckles and or fist in to any orifice of choosing.

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.

Knucklebuster

A car, usually an old American car (1930's-1970's) who seems determined to skin, slice, and slash the hands of every mechanic who touches it, regardless of their skill-level. Resistant to tools, penetrating oils, vice grips, and laws of physics. Any bolt that is in this car will STAY in this car, whether you want it there or not, and if you try to remove it, it WILL break off, and leave you requiring 15 stitches in the process.

Holy Hell.........that '49 Mercury just tore my whole hand open, and all I was trying to do was change her damn oil!! What a knucklebuster!!

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!
