This short flap comes from R.E.P.O., the cooperative horror game where players loot haunted locations while avoiding dangerous creatures, including a small enemy duck that can suddenly take flight. Clips of that moment began circulating in gameplay videos and short-form edits, where the brief, almost comical flutter stood out against the game's tense atmosphere. Because it is so short and easy to recognise, creators keep reusing it as a quick audio cue for escape, surprise and absurd movement, long after the original clip has passed.
