Frog's Knuckle

The crease of your pants, separating where the two balls are, stretching the sack like a frogs webbed foot.

mass knuckle

Moose knuckle or camel toe, but in the back. As if someone was wearing spandex and hiding two bagels between their legs just under the grundle.

“Oh man, this woman flossed a wicked mass knuckle yesterday at the swap meet.”
