An injury sustained by a friend that would usually elicit concern and compassion but instead makes the friend the target of ridicule because of the idiotic manner in which the injury was received.

Brian: Dude, what the fuck happened to your leg? That looks nasty!

Matt: Oh yeah dude, I was wasted and I decided to jump off the back of a dump truck into a cougar nest.
