The chant comes from Dragon Ball Super: Broly, the 2018 animated film that reintroduced Broly as a powerful Saiyan exiled from Planet Vegeta. During the final battle the repeated Go Broly vocal hook became the most quoted musical moment, separate from the dialogue. Clips of the chant spread through YouTube edits and later TikTok, where users paired it with workouts, sports highlights and other anime fights. Its simple repeatable wording made it easy to loop, remix and recognise even without seeing the movie.
