When your junk is hanging out of your pants; when a man's genitalia is exposed
"I watched TV with Johnny for 20 minutes before I realized he was hanging crumpet. Disgusting."
The act of a male demonstrating his nonchalant aura/well-being by accidentally displaying one of his testicles from his loose hanging briefs. Usually occurs in the morning after a night-out or a sleepover.
Male 1: Ew, dude put it away
Male 2: What?
Male 1: Your totally hanging crumpet
Male 2: Sorry bro, I'm just so relaxed
