Little is documented about who first uploaded Rotoudokuu, and its French description frames it only as a burp from a unicorn queen, which has become the whole identity of the clip online. The nonsense name gives searchers a unique label to share, while the short runtime makes it easy to drop into soundboards and meme edits. It survives because burp jokes are universal and the royal unicorn framing makes this one feel distinct from a plain burp effect, letting creators reuse the same tiny gag in many different contexts.
