This sound is associated with osu!, the popular rhythm game released for PC in 2007. The phrase is best known as a startup or menu voice line, which made it memorable beyond regular gameplay. Over time, players and meme editors began reusing it in short clips about reinstalling the game, returning after a break, or instantly recognizing the interface. It remains popular because even a five-second clip is enough to signal osu! to fans, much like other instantly recognizable game audio such as the ROBLOX oof.
