Known online under the name Trouloris, this sound comes from the French phrase meaning an enormous hole. It circulated on French-speaking meme soundboards as a short reaction clip rather than from a specific film or show, and its appeal is the deadpan, distorted pronunciation. Creators keep reusing it because the line works literally for holes and falls, and figuratively for gaps in logic or missing content in edits. Similar short reaction clips like the bruh sound effect are often paired with it in meme compilations.
