There is no documented source for this clip, so it is best understood as an internet meme sound rather than a line from a film or show. It circulates on soundboards and in short-form edits as a gotcha punchline, where the name itself does much of the comic work and the short length makes it easy to drop at the end of a joke. Its staying power comes from that flexibility: it can tease a friend, cap a prank or punctuate a twist without needing any setup, which keeps it useful long after the first wave of posts.
