With no clear single source behind it, rhehehehehe has spread mainly as a short, shareable reaction clip on meme soundboards and in short-form video edits. Its appeal is its simplicity: a one-second laugh needs no context, translates across languages, and fits neatly at the end of a joke or over a failed stunt. That portability has kept it in rotation for reaction videos, prank compilations and gaming clips, where creators reuse familiar laughs to signal amusement without adding dialogue.
