The origin of the Raiki clip is undocumented, and like many soundboard uploads it appears to have been named by whoever first shared it rather than by any source. Its raw title, written in Korean as 라이키, gives no clear pointer to a show, game or creator, so the sound has spread purely through reuse: listeners hear it in an edit, look it up, and add it to their own boards. That grassroots path is typical of viral meme audio, and it is why the clip keeps circulating in reaction videos and stream highlights despite having no confirmed backstory.
