PaRappa the Rapper is a PlayStation rhythm game first released in 1996, starring PaRappa, an optimistic paper-thin dog who learns to rap his way through everyday problems. His short 'Oops' line comes from that cheerful, cartoonish world and has since been lifted out of the game as a standalone reaction clip. Shared on soundboards and in meme edits, it is used far beyond its original context because it is instantly recognisable to players and immediately understood by everyone else as a small, harmless mistake.
