Too Stupid To Be Alive

Just... just...

This is used to describe someone who commonly does things that endanger their life, like mindlessly screw around with fire. This person is most likely to be an Ass of some sort: a Dumbass, Jackass, or Asshole. A Dumbass would be Too Stupid To Be Alive because it's their job, a Jackass because they think they can do risky stunts without getting hurt, and an Asshole because they're supposed to get their comeuppance after doing something dangerous in an attempt to get someone else hurt, not themselves.

This applies very well to the Horror Victims in horror movies. At this point, we hope that the Horror Monster gets them because of how infuriating it is to watch them do the most moronic things imaginable yet still somehow live.
