The phrase means three more and we leave, a familiar way of announcing a final countdown before a group departs, and that everyday meaning has helped the clip travel as a short reaction sound on soundboards and social videos. Creators tend to use it as a punchline for leaving, ending a stream, or cutting away from a scene that has gone on long enough. Because the line is short, clear and instantly understandable to Spanish speakers, it keeps working as a quick closing gag without needing any setup or context.
