Fuzz Knuckle

One who speaks ridiculous obnoxious jibber-jabber, making you want to fiercely smack them and burn their chickens.

Pinky: "WTF?! It rains in the ocean???

Zane: "Dude, shut up fuzz knuckle, or I'll burn your chickens"

Two Knuckle Shuffle

The Two Knuckle Shuffle is where a man shoves his 2 knuckles all the way up another man's asshole and starts taking his 2 Knuckles and the other man slowley starts clapping.

knuckleball

The sexual act where you spread your partners rectal flaps with the knuckles of your index and fore finger, then cum with the screwball on a count of two balls and one strike.

The bases were loaded so I slipped her a knuckleball. Garth, she definitely won't be walking home any time soon. Two balls, on strike, and I'm out - she was like WTF!

knuckle bump

To snort a small amount of cocaine from the creases of your knuckle. Usually the most discreet way to snort in public (club, party, street) so that no one will suspect anything.

Ben: Did you see that chick knuckle bump?

Tice: I sure did.

Knuckle Sludge

Extending one's finger and ramming said digit into the anus until the knuckle reaches the rectum.

Nothing beats reruns of "Welcome Back Kotter" and gettin' the ole' Knuckle Sludge.
