Mahjong Soul is an online mahjong game where players compete in matches using anime-style characters, and Ichihime is one of its early, recognisable characters, a cheerful cat-eared girl who has become a fan favourite. In mahjong, calling ron declares a win on an opponent's discarded tile, so the line naturally became shorthand for victory among players. Shared through gameplay clips, streams and soundboards, it is now used well beyond the game itself as a compact, upbeat way to mark a win or a lucky break.
