The male version of "camel toe". Where said male's pants are so tight and/or transparent, the shape/details of their anatomy are clearly visible even through the garment, resembling the appearance of a moose's lower ankle (or "knuckle").
"When I watched wrestling last night, that tag team had on spandex shorts SO tight, they were sporting some SERIOUS moose knuckle!!!"

A much larger version of the camel toe. Typically seen when a fat woman or a slightly heavier woman wears tight jeans and the saggy area around her vagina forms what looks to be camel-balls.
Damn! Girl could have looked in the mirror before she walked out the door looking like that! If I had known better, she was packing a set of balls, cause that moose knuckles she was sportin' was huge!
