The phrase translates from Spanish as 'what, what, what was that?', a natural way of reacting to something strange or hard to believe. Online, the short clip circulates as a Spanish-language reaction sound, shared in memes, short videos and chat audios whenever a creator wants an instant expression of disbelief. Its appeal comes from repetition: asking the question three times makes the confusion sound funnier and more dramatic than a single question would. Because it is only about a second long, it fits easily at the end of a setup or over a surprising cut.
