The exact origin of this clip is not documented, and it circulates mainly as a short user-uploaded reaction sound rather than as a line from a known show, film or song. Its appeal comes from its simplicity: a single stretched sound with no words can fit almost any moment of doubt, delay or mild disbelief. That flexibility has kept it in use in meme edits, reaction videos and short-form clips, where creators need a quick audible shrug without interrupting the visual joke.
