This clip comes from the MUGEN fighting game scene, where Kung Fu Man is a well-known stock character used to test new stages and fighters. The KO moment is the universal end to a MUGEN match, so the sound travelled with gameplay videos, edits and meme compilations shared by fighting game fans. Because the knockout is instantly recognisable even without context, editors keep reusing it to close out defeats in gaming clips, reaction videos and short-form edits, where a quick, decisive finish works better than a long explanation.
