The phrase itself is everyday Spanish slang for calling out something foolish, and that familiarity is part of why the clip travels so well in Spanish-speaking chats and social videos. As a short reaction sound, it works without translation for many listeners because the tone carries the meaning even before the words do. Creators reuse it for fails, bad takes and absurd comments, and it keeps circulating because it fits almost any moment where disbelief is funnier than anger.
