With no clear credited source, the rehehehe laugh spread as a generic meme laugh on soundboards and short-form video, shared under repeated spellings of its giggle. Its appeal is its brevity and recognisability: a second of stuttering laughter reads immediately as mischief without needing context or dialogue. Creators reuse it across gaming clips, cartoon edits, and reaction videos to mark a character as scheming or delighted by chaos. Because it functions more as punctuation than speech, it has stayed useful even as the trends around it change.
