There is no widely documented source work behind this clip, and it circulates mainly as a short reaction sound rather than a quote tied to a specific show, film or creator. Its appeal comes from the phrase itself, a common Spanish way of asking what thing or what is that, made funnier by the drawn-out ending that turns a simple question into an exaggerated reaction. Short reaction clips like this travel easily between memes, edits and chat replies, which helps explain why a clip under a second long keeps appearing whenever something confusing needs a quick, recognisable response.
