Secret ending spread as a generic meme button on soundboards, built from the idea of hidden endings in games where players expect a rare cutscene after finishing extra conditions. Online, the clip became shorthand for an anticlimax, shared in edits that promise a big reveal and deliver a tangled meme mashup instead. Its appeal links it to other joke buttons like a classic meme sting and goofy ahh sounds, which also rely on instant recognition. It remains popular because almost any serious setup can be undercut by playing it at the reveal moment.
