Youth Is Wasted on the Dumb

Characters (adolescent or young adults, usually) get together to do something manifestly dumb and often prohibited, but hey, they're young and so immortal, aren't they? The hold-outs are often persuaded because they don't want to look like a Dirty Coward, and often one of the bolder characters urges it's Not Cheating Unless You Get Caught. Visiting an abandoned house or performing a ritual are common. Bullying a Dragon can be a form of it; you're not afraid of him just because he can warp space-and-time with his thoughts! The Call Receival Area and the Forbidden Zone are popular destinations. A particularly idiotic Wild Teen Party may feature one, especially if the participients got very, very drunk.

Occasionally performed by a solitary figure (but even then he often bragged about it beforehand).

Popular Horror Trope. Often makes them Too Dumb to Live. "Hey everyone, we should so go to the abandoned camp ground where dozens have been slaughtered in the last year and have a party with bad music and alcohol! Afterwards, we'll all split up and have sex!!"

Compare Kimodameshi. Scare Dare involves even younger characters, children, and is much less likely to be dangerous.

Contrast Deadly Prank, where someone else is imperiled. If whatever they do ends up backfiring and yet they get out of it without a scratch, then it's No One Should Survive That.

Note: does not cover shows that set challenges; this is something the characters dream up of their own stupidity.

Because this is very, very, very much Truth in Television, no need for Real Life examples. If you really want Real Life examples, try looking at the Teens Are Monsters page.
