Death by self stupidity
When a person dies as a result of performing stupid stunts, or anything else that a someone of more common sense wouldn't do.
Guy 1: Did you here about that guy who died trying to resusitate a liger? Guy 2: Yeah, poor bastard, it tore his face right off, raped him, and then ate him. Guy 1: It's a shame really, just another death by self stupidity..
