Cha Cha Cha was written for Käärijä, the Finnish rapper and singer who performed it at the Eurovision Song Contest 2023 in Liverpool. The song finished second overall after winning the public televote, and its repetitive hook and cha-cha inspired staging made it instantly shareable. Clips of the chant spread across TikTok and YouTube Shorts during the contest week, then stayed in use as a meme sound for dances, entrances and ironic celebrations long after the final.
