The clip comes from VTuber Raki Kazuki, whose loud vocal outbursts became popular as standalone reaction sounds in anime and streaming communities. Short screams like this RAH spread through soundboards and short-form edits because they are instantly recognizable and need no setup to understand. Fans clip the moment, isolate the clean yell, and reuse it across unrelated videos as a universal signal for hype, anger or sudden determination. Its brevity and intensity have kept it in rotation alongside other anime scream effects long after the original stream.
