This clip is based on an edited Kefka laugh, referring to Kefka, the villain from Final Fantasy VI. Online, the laugh became useful as an exe meme sound because its manic delivery fits corrupted, demonic, or glitched joke edits. Short cuts of the laugh spread across meme compilations, gaming edits, and reaction posts where creators wanted a quick signal that a scene had turned sinister or absurd. It still gets reused because the sound is instantly readable even in very short videos.
