Chui peng is a common Chinese expression meaning to flatter or praise someone excessively, often with an implication of insincerity or self-interest. Online, the short spoken form has become a handy reaction clip in edits and comment-style videos, especially where Chinese-language meme culture mixes with gaming and social clips. Its appeal comes from brevity and tone rather than a known source performance, so creators reuse it as a generic label for toadying behaviour. It remains popular because a single phrase can reframe praise as mockery without needing explanation or subtitles.
