The ohohoho laugh has circulated online as a generic reaction sound rather than a clip tied to one confirmed source. Its repeated syllables make it instantly recognisable even without context, so it spread through meme edits, soundboards and short videos as shorthand for smug laughter. Creators reuse it when a character acts superior, teases someone or celebrates a tiny win, because the tone communicates the joke faster than dialogue. That flexibility across anime edits, gaming clips and reaction posts is why the short laugh keeps resurfacing.
