The line comes from Pokemon Stadium, the Nintendo 64 game that staged Pokemon battles with a full play-by-play announcer calling each move as it happened. In that context, a barrage warning signalled a multi-hit attack was coming, giving the commentary a sports-broadcast feel that players remembered long after the match. Soundboard users later lifted the short call for its dramatic timing, and editors now reuse it whenever a scene needs a sudden escalation, because the familiar announcer voice instantly frames what follows as an incoming flurry.
