This sound is associated with Kiko, the Brazilian Portuguese name for Quico from the sitcom El Chavo del Ocho, which became hugely popular across Latin America and Brazil through dubbed television broadcasts. Clips of Kiko's irritated delivery spread widely in meme edits, reposts and group chat videos because the line is short, expressive and easy to drop into conversations. It remains popular online thanks to the character's recognizable voice, the show's long cultural life, and the way classic TV audio still powers fast reaction memes.
