The phrase is Spanish for a garbled version of who is Chile, with eh replacing es in casual speech, which is why the clip circulates mainly in Spanish-language meme spaces. It has no confirmed performer, show or film source attached to the upload, so its spread comes from reposting as a short reaction sound rather than from a single viral scene. At about ten seconds it is longer than most one-line drops, and creators tend to reuse the same drawn-out delivery for mistaken identity jokes, geography mix-ups and confused reply threads online.
