Usagi is one of the main characters in Chiikawa, the Japanese manga and anime series about small, cute creatures living an everyday life filled with strange and funny moments. Known for a loud, excitable personality, Usagi often shouts and cheers in a high voice, and fans have clipped those outbursts into short meme sounds. This sped-up version circulates on soundboards and in short video edits, where its frantic rhythm makes it useful as a reaction to excitement, panic or sudden chaos rather than as a recognisable line of dialogue.
