Exactly What It Says on the Tin - this is when someone attempts to kill themself, and fails. This may lead to them trying to kill themselves again, or maybe they'll see it as a sign and go their merry way. It's not Interrupted Suicide; they go through with it... they just don't die, for whatever reason. It may be because of some kind of immortality, or maybe the means they used weren't effective enough. People who are physically not able to die for some reason usually cannot kill themselves no matter how hard they try. If done well, this can be either touching or tearjerking... and if done badly, it can just seem like the writers didn't have the guts to kill a character off. Occasionally Played for Laughs.
