Uma Musume Pretty Derby began as a Japanese media franchise by Cygames, with an anime series in 2018 and a mobile and PC training game released in Japan in 2021. In the game, players train anthropomorphic horse girls based on real racehorses and raise their speed, stamina and other stats between races. Interface sounds like this status up cue became familiar through gameplay videos, streams and social media clips. Its association with successful training made it a recognisable shorthand online for improvement, power ups and satisfying progress in edited videos.
