The clip comes from a voice changer recording, with the artist credit pointing to an online voice effects tool rather than a film, show or known creator. Because the word and its source are so minimal, its life online has been shaped by editors reusing it out of context on soundboards and in short videos. A single spoken myself works for almost any self referential joke, which is why the sound keeps appearing as a quick insert instead of being tied to one specific meme or moment.
