Rou bian qi is the Mandarin reading of characters that spell niku benki in Japanese, a term long circulated in adult doujinshi, eroge and translated hentai forums before moving into general meme slang. As Chinese and Japanese fandoms overlapped on video and chat platforms, the phrase was clipped, reposted and turned into a standalone reaction sound detached from any single scene. Its continued use comes from that portability, as listeners who recognise the slang get the joke instantly while others hear only an abrupt, odd foreign phrase.

A very short voice clip saying rou bian qi, a vulgar Chinese slang term from adult anime culture, often used as a shock reaction sound in meme edits.
This is a brief spoken clip lasting under a second, built around the three syllables of rou bian qi delivered in a flat, abrupt burst. The phrase itself is crude slang borrowed into Chinese from Japanese adult fiction, where it is used as a degrading label for a character treated purely as a sexual object. Heard out of context the sound works less for its literal meaning and more for its shock value, landing like a blunt insult or punchline that stops a scene, makes viewers pause, and signals that the edit has turned deliberately vulgar and absurd.
