Was dat een scheet is Dutch for was that a fart, and the clip circulates online purely as a reaction sound rather than from a widely identified film or show. Short Dutch phrases like this spread through soundboards, group chats and short videos because the meaning is clear even to many non-Dutch speakers from tone alone. It stays popular for fart jokes, awkward silences and blame gags, where the innocent question does more comedic work than an actual fart sound effect would on its own in edits.
