Online, one more thing has become shorthand for a final surprise that was not in the original plan, and creators use the short clip to signal that the video is not quite over yet. It spread through short-form edits, reaction videos and meme compilations, where a two-second audio cue is enough to reset attention before a last joke, reveal or blooper. Its appeal is its familiarity: viewers already know to expect something extra, so the sound works across comedy, gaming, tutorials and everyday vlogs without needing any explanation.
