Hey Oh was released by French R&B duo Tragédie in the early 2000s and became one of their best-known singles, with its simple oh-oh-oh chorus making it easy to remember and sing along to. Years later, the short vocal hook was clipped from the song and shared on soundboards and short-video platforms, where its upbeat, slightly dramatic tone made it a natural fit for entrances, reveals and reaction edits. It survives because the chant is instantly recognisable even without the full song, and it sets a playful mood in just a couple of seconds.
