The 'sore sore' chant comes from Tsukiusa, a Japanese virtual idol known as 月兎 whose voice samples circulate among fans as short reaction clips. 'Sore sore' itself is a common Japanese encouragement phrase, similar to saying 'go go' or 'that's it,' often heard at sports matches, festivals and idol performances. As a standalone soundboard clip, this two-and-a-half-second sample is shared for its cute, high-spirited idol delivery rather than any single famous broadcast. Its brevity makes it easy to drop into edits, streams and memes.
