As a TikTok trend sound, Están raros circulates mainly in Spanish-language short videos, where creators use the phrase to flag behaviour that feels off, inconsistent, or unexpectedly strange. Its appeal comes from its simplicity: the wording is short, instantly understood by Spanish speakers, and easy to drop over almost any awkward scene without needing extra context. Because the line works as a general reaction rather than a reference to one specific event, it has stayed useful across different formats, from comedy sketches and reaction clips to everyday moments filmed with friends.
