The line comes from Daria, a character in Rune Factory 3, the farming and action role-playing game for Nintendo DS. Fans clipped her stretched rainbow exclamation because the delivery sounds like the classic elongated shout heard in anime and game memes. Shared on soundboards, it joined a family of short cheerful reaction clips alongside the familiar cartoon yell style. Editors still reach for it when a moment needs instant color and joy, since the recognizable game voice gives even simple edits a playful nostalgic spark.
