Moose Knuckle 

A very noticeable bulge beneath a tight clothed males waist line, more popularly known as a hard on or erection. Due to the restricted room for the dicks extension, it fails to fully protrude outward, thus, remaining hindered and resembling an intriguing mound-shaped growth instead. Women have camel toes and men have moose knuckles (which is actually pertaining to the knee on a moose).

"Oh my GOD girlfriend, did you see the size of that moose knuckle that guy was carrying around under his speedo?"

Douche Knuckle 

A cross between a complete douche and somebody stupid, proven more effect at winning an argument than two camels in a tiny car.

The Fuckle Knuckle 

The act of penetrating both a woman’s anus and vagina with two fingers each, on the same hand. The hand should be held stiff and look like a curved “live long and prosper” hand sign.

“Yo I did the fuckle knuckle on suzy last night”
“Doesn’t your hand hurt bro???”
“Yeah but the carpal tunnel is worth it”
