Grand Blue began as a manga by Kenji Inoue and Kimitake Yoshioka in 2014 before its anime adaptation aired in 2018, following Iori Kitahara and a university diving club drawn into rowdy, alcohol-fuelled comedy. Short shouted clips from the series spread easily on soundboards because the performances are loud, expressive and understandable even without context. Vamos is widely used across Spanish and Portuguese-speaking sports culture as a chant meaning let's go, so the clip works far beyond anime fans as a universal hype and celebration sound online.
