Thommot fart has no widely documented origin in a film, show or viral video, and it circulates mainly as a short user-uploaded clip on soundboards. Its label appears to be a playful or misspelled name attached to a generic comedic fart effect rather than a reference to a known character. That anonymity has helped it spread, because creators can reuse it freely as a universal prank noise without needing context. It remains popular for the same reason many simple gross-out sounds do: it is instantly understood, easy to time, and reliably funny in memes, streams and short videos.
