The line comes from Dikkenek, a 2006 Belgian comedy film that became a cult favourite in French-speaking Belgium and France, and it is closely associated with François Damiens. In the film, the farewell is delivered with comic bluntness, and that tone helped it travel beyond the cinema as a quotable punchline. Online, creators adopted it as a way to signal that a subject is closed, a debate is over, or a joke has reached its end. Its brevity, lasting under a second, makes it easy to drop at the end of clips, reaction videos, and memes without explaining the reference.
