moose knuckle

A unambiguous, often mesmerizing knuckle-like protrusion from a male crotch, usually dependent on the tightness of the offender's clothing. Moose knuckles are most common in males with large testicles, or men who fail to tuck successfully while wearing Spandex.

I have never seen a bigger moose knuckle; it looked like two balloons stuffed inside a ziploc.
