The exact origin of this short clip is not documented, so it is best understood as a reaction sound that circulates on soundboards and in meme edits rather than as a line from a known film or show. Its appeal comes from the familiar situation it captures, being accused of something and denying it straight away, which makes it easy to reuse in many different jokes. Creators keep returning to it because the denial is short, clear and instantly recognisable as a punchline, whether it appears in a chat reply, a gaming clip or a short video.
