Sometimes when a character, especially a Sad Clown or Plucky Comic Relief type, is facing death, they find the whole experience laugh-out-loud funny. Or sometimes, the laughter itself is what kills them, especially if they've just been hit with Comedy as a Weapon. Either way, that's where this trope comes in. Can also overlap with Laughing Mad, especially if the character is a villain who plans on Taking You with Me. Laughter may be their way to Face Death with Dignity.
Compare Dying Smirk, Go Out with a Smile and Comfort the Dying. Contrast Laugh Themselves Sick, which doesn't (usually) involve any actual injury. Although a plausible reaction if played right, this trope is not to be confused with the Horror Comedy Tabletop RPG of the same name.
This is a death trope, so expect unmarked spoilers.
