Fall Guys was released in August 2020 by British studio Mediatonic, with its clumsy bean contestants and bright obstacle courses quickly becoming a streaming hit. The beans communicate only through short woo and wow noises, which players clipped and shared on TikTok, YouTube and Discord as reaction sounds. Like the ROBLOX oof, it became shorthand for a playful fall or mistake rather than real pain. Its continued use comes from that instant recognition, even in clips from completely different games.
