The unsightly bulge created in the crotchal area when a man's pants are far too tight.
The
moose knuckle is particularly evident in middle-aged men in suit pants or Wranglers.
If your friend says something about someone having a mooseknuckle,
don'
t judge them for looking at an older man's crotch. It's like a bad car accident. You
don't want to see what happened, but you can't pull your eyes away.
