Pestañaste circulates on TikTok as a short RKT-style clip associated with DJ Braian, where its file credits link the hook to that dance sound. It spread through short videos that play on the Spanish word for blinking, using it to mark the exact second someone misses something or zones out. Because the clip is only about three seconds long, it fits easily at the end of a joke or before a goodbye, which is why creators keep reusing it for quick reaction edits, fail moments and sleepy punchlines rather than as a full song.
