There is no clear, widely documented source for this short clip, so it is best understood as an online meme sound rather than a line from a specific film or series. Its length makes it easy to reuse, and it has circulated mainly through short-form edits, reaction videos and soundboards where creators need a fast, recognisable cue for dark or dramatic humour. That flexibility is why it has stayed in use: it does not depend on knowing a particular scene, only on recognising the mood it signals in a few seconds.
