A very noticeable bulge beneath a tight clothed males waist line, more popularly known as a hard on or erection. Due to the restricted room for the dicks extension, it fails to fully protrude outward, thus, remaining hindered and resembling an intriguing mound-shaped growth instead. Women have camel toes and men have moose knuckles (which is actually pertaining to the knee on a moose).
"Oh my GOD girlfriend, did you see the size of that moose knuckle that guy was carrying around under his speedo?"
