The phrase zou si ni is a colloquial Mandarin threat that has circulated online as a short reaction clip, separate from any confirmed film, show or game source. Its brevity and intense delivery made it easy to lift, loop and share on soundboards and in short form video edits. Creators use it as a shorthand for mock rage, similar to other angry Chinese phrases that travel as memes even among viewers who do not speak Mandarin, because the tone alone communicates the joke clearly.
