The sound is listed under the name Sorashina Sopia, and it circulates online as a short, shareable reaction clip rather than as part of a longer song or scene. Its appeal comes from the directness of the Japanese word fuzakena, which is widely recognised in anime and streaming communities as a forceful way to say stop messing around. Short clips like this travel easily between edits, streams and social posts, where a single emphatic voice line can carry the joke, and that portability is why the shout continues to be reused by creators who want an instant, expressive interruption.
