Too Stupid To Be Alive

''You keep doing that, you'll die! (thing happens) Told ya.''

This is used to describe someone who commonly does things that endanger their life, like screw around with electricity or fire. This person is most likely to be an Ass of some sort: A Dumbass, Jackass, or Asshole. A Dumbass would do these things because they're stupid, a Jackass because they think they can do risky stunts without getting hurt, and an Asshole if they're like a Jackass but they're supposed to get their comeuppance.

This applies very well to people 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.
