The joke at the centre of this clip comes from Nintendo's own naming: the Wii console, the Mii avatars players created on it, and the later Wii U, whose name only makes sense as a follow-up. By denying the first console ever existed and then arguing that without Mii there would be no U, the speaker turns that naming chain into a piece of mock logic. Shared as a short meme sound, it is most often reused by gaming creators and commenters who want a loud, quotable way to parody an argument that sounds certain while falling apart.
