Little is publicly documented about the exact origin of the C8 Lu Ma clip, and its title appears to come from a user-generated soundboard rather than a widely known film, show or song. That is common for short reaction clips, which often circulate first among small online communities before being copied, remixed and reused in short videos. Its three-second length makes it easy to save, share and reuse, so it has found a small but steady audience among creators who need a quick, recognisable cue without a long setup.
