"Proute" is best understood as a label for a brief fart joke sound rather than a clearly documented clip from a known film, show or creator. The term itself is common in French as a playful way to say fart, which is why uploads with this name appear in meme and soundboard spaces. Its staying power comes from how universal the joke is: creators can drop a split-second fart sound into reaction edits, prank clips and fail videos without needing any extra setup.
