The clip comes from the BanG Dream franchise, where Ichigaya Arisa is the tsundere keyboardist of Poppin'Party and Kasumi Toyama is its energetic guitarist and vocalist. Arisa constantly scolding Kasumi became a running dynamic in the anime and the BanG Dream Girls Band Party game, making their exchanges popular with fans. Short shouts like this spread through bandori communities and soundboards because they capture that relationship in seconds. It remains used by editors who want an anime reaction that needs no context beyond an angry friend calling out another.
