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.

While engaging in rear-door entry with a female partner, have an acomplice hide (preferably in a closet). With your two hands spread out, position them over her head like moose antlers. Have the friend jump out of a closet with a camera (flash required) to take a picture, one that resembles a spooked moose. variations can also be played out resembling a deer

The next level of camel toe. That is to say, that the camel toe is popping out so far, that it is no longer in the same league as ordinary camel toe.
