No documented source or original creator is attached to this short clip in the available records, so it is best understood as a user-shared soundboard item rather than a line from a known show, film or song. Its spelling, with the extended final letters, points to the way it circulates online, where short, exaggerated sounds are saved, renamed and reused across edits. At just over five seconds, it fits the quick-reaction format favoured by meme creators, and its continued use comes from that compact length and instantly recognisable stretched ending.
