OMG is the title track from NewJeans single album of the same name, released in January 2023 by the South Korean girl group. The song quickly became a global K-pop hit, helped by its catchy chorus and the group's relaxed, youthful image, and short clips of it spread widely on TikTok and short-form video platforms. Fans used it for dance challenges, edits and cute everyday moments, which kept the hook familiar even outside the full song. Its short, bright snippet works well on soundboards because listeners recognise it instantly.
