The phrase comes from Vietnamese television, where it is linked to a Thach Thuc Danh Hai comedy performance built around Tay Du Ki, the Journey to the West story, including a young monk character. In that setting, the announcement marks the moment a performance runs out of time, which is why short clips of it spread among Vietnamese comedy and editing communities as a ready-made ending. It remains popular because the line is short, clear, and immediately understood as a deadline, even in a fast meme edit.
