No widely documented source has been attached to this short phrase, so it is best understood as an internet meme sound rather than a line from a named film, show or song. Short Mandarin joke clips like this circulate through soundboards, messaging apps and short-form video edits, where users reuse them without needing the original context. Its appeal comes from brevity and shock value: a single blunt phrase can reset the tone of a clip in less than a second. That portability helps explain why it keeps appearing in reaction edits despite its small audience.
