A derogatory term for the size of a woman's sideways sloppy joe. It is when a woman's cooter cleavage is clearly visible through her form-fitting clothing, aka spandex. It is definitely a hot fashion statement.
Man, I thought my weiner looked big when I wore speedos, but that chick's moose knuckle has got me beat by a long shot.

in yiddish this means a man that has his pants hiked up too far and has split the difference in his bean bag leaving one nut on either side of the crotch seam causing the individual nuts (you'll have to sit this one out hitler, sorry) to hang low and give that 'sad puppy dog eyes' appearance to the nutsack. most often associated with older men in slacks with belts.
grandpa- fuck dude, reunite your nuts. your pants are like the berlin wall of nutsacks. tear down the wall! tear down the wall! tear down the wall!

A male version of camel toe
Dude, your jeans are so tight your moose knuckle is showing

A man's version of a camel toe. The result of wearing spandex, or pants that are way too tight--resulting in an unsightly bulge of his junk.
Check out the moose knucks on that freak!

The male version of a cameltoe. Usually found on older rotund gentlemen wearing a suit.
That guy in the business meeting was so big, his moose knuckle was sticking out of his front of his pants and it looked like a fanny pack gone wrong.

Canadian Word to describe a man whose pants are so tight that his 'package' stand out or bulge.
Dude, that dudes pants are so tight he's got a mooseknuckle. What an fagmaster that guy is.

Simply put it is the male equivalent of a woman's camel toe. Usually caused by the seam of tight but thin leg wear such as spandex, the testicles and penis form two bulges on opposite sides of the seem that vaguely resembles the hoof, or "knuckle" of a moose. hence "Moose-knuckle"
Jon didn't wear underwear under his skintight Peterpan costume, and everyone could see that he had a moose-knuckle.

Close cousin to the cameltoe, its the outward migration of meaty mudflaps upon introduction of fabric to the crotch of your typical 'split-tail'. Actually very common in the Midwest, most likely to be found at your local club on 80's Night.
Holy shit man, I bet that chick's Mooseknuckle chokes like a boa constrictor.
