A golden hedgehog is when you're a C-level executive and you do something incredibly stupid like sleeping with a direct report and you get fired and you don't get a golden parachute, you get NOTHING...also known as a Golden Hedgehog
Dude did you hear about James Dickwad III. He just got fired for sleeping with Lisa! I hope he doesn't get a golden parachute. Naw that dumbass walks away with nothing. A golden hedgehog.
