Bubble is the title track from South Korean girl group STAYC's third mini-album Teenfresh, released in 2023. The song's playful, fizzy concept matched its bright pop sound, and fans quickly picked up its catchy chorus for dance challenges and short-form edits across social platforms. Its short, punchy hook travels well outside full performances, which is why it keeps appearing in fancams, transitions and upbeat compilations long after its promotion period ended.
