The exact source of this short clip is not clearly documented, so it is best understood as a generic automatic weapon sound rather than a line or moment from a specific film, game or show. Short gunfire effects like this circulate widely on soundboards and in editing libraries because they are instantly recognisable and easy to drop into almost any scene. Their appeal has lasted because a brief burst of fire needs no explanation, working equally well for serious action edits, gaming highlights and ironic meme videos where the sudden noise is the joke itself.
