Moose Knuckle 

The broader larger version of a camel toe. Often referring to a woman with a meatier gap from thigh to vulva, also used in accordance with heavy set females.

This term is seemingly being misused for a male equivalent which actually has multiple derivative terms.
Refer to Lobster Claw or Mammal Toe for male definition. Also males bearing the mark from restrictive lower garments are referred to as Grape Smugglers (also just referring to the garment like Ruster or Wrangler jeans).

Citing Seth Rogen and Diana Bangs characters in The Interview

DB: "I particularly enjoyed the Miley Cyrus "Cameltoe" episode, very deep."
SR: "Very deep! Yeah she has quite a hearty moose knuckle!"

Spunk Knuckle

Someone who vigorously masterbated frequently. Also, has no scruples for the time or place that the masterbatory overtones eminate from.
Places to cath these deviants:

The porta-potty at a Britney Spears concert.

A bathroom stall during the senior prom.

The toilet while at a raging party.

In the parking lot waiting for a friend to buy a soda at the mini-mart.

At a sleepover at a friend's house while everyone is asleep.

Your mom's house during dinner.

Jimmy is such a SPUNK KNUCKLE. He was caught jerking himself by my aunt in the bathroom stall at the funeral for her dead cousin. What a Battered Cavern!

Moose knuckle 

An unusually large pussy that has little elasticity from being fucked to much, and rears its ugly head in tight apparel like yoga pants.

That chicks Pussy was so big that in her yoga pants at the gym she didn't have a camel toe, she had a moose knuckle.

Moses Knuckle

This is the opposite of Moose Knuckle in boys. Its when the men who guard the ass fort are being seperated by a thonglike structure and protrude from each side like Moses parting the sea of swimmers (testes).

Wow.. that guys grapesacks (euro-panties) are totally giving him a Moses Knuckle.
