The line comes from Pirates of the Caribbean: The Curse of the Black Pearl from 2003, where Captain Jack Sparrow discovers that Elizabeth Swann has burned his stash of rum to create a signal fire. His incredulous question became one of the film's most quoted moments and later spread through reaction videos, edits and soundboards as shorthand for discovering something valuable has vanished. Because the delivery is so short and recognisable, creators still use it decades later whenever an empty container or a ruined plan needs an instant, funny reaction.
