The sound comes from Hollow Knight, the 2017 metroidvania by Team Cherry set in the ruined kingdom of Hallownest. Enemies that hang overhead and drop on the player became a familiar threat during exploration, and their short explosive cue was clipped by players for soundboards. It spread through gaming edits and meme compilations where a fast, recognisable burst was needed for a surprise fall or failure. It remains popular because Hollow Knight fans instantly recognise it, while other viewers just hear a clean, funny pop.
