that inhalation on your doomsday before you heart finally stops beating
Raven: then you know what I'm here for?
Death: ...but they're mine now, once they took their last breath, I'm a soul collector baby I'm Death

Used often to describe fan games adding more (and often very unnecessary) phases to an otherwise finished boss fight. Derived from the Undertale fan game, "Last Breath", in which its sub-community makes absurd amounts of fan made phases that exaggerate sans' durability and endurance to the point that it is a joke.
"Dude lets make vs tricky phases 5 and 6."
"Ever heard of Last Breath Syndrome?"
"No."
"Search it up."

it is basically the undertale sans fight but 10000 times more hell
Person 1: Hey have you finished the sans fight
Person: No, but I have finished Undertale last breath
Person 1: IMPOSSIBLE IT IS TOO HARD TO BEAT
