There is no widely documented original source for this clip, so it circulates mainly as a user-uploaded soundboard snippet rather than a quote from a known show or film. The phrase itself is everyday Mandarin, which is why it works as a universal ending cue even for viewers who do not speak Chinese. Short meme audio like this tends to spread through edits, streams and reaction videos, where a crisp one-second closer is more useful than a longer line. Its staying power comes from that simplicity: anyone can understand that something just ended.
