look up any word, like tribbing:
 
65.
A unambiguous, often mesmerizing knuckle-like protrusion from a male crotch, usually dependent on the tightness of the offender's clothing. Moose knuckles are most common in males with large testicles, or men who fail to tuck successfully while wearing Spandex.
I have never seen a bigger moose knuckle; it looked like two balloons stuffed inside a ziploc.

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!

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"
