The exact recording behind this upload is unclear, as it comes from a user-generated soundboard, but the peko verbal tic is widely associated with Hololive VTuber Usada Pekora and her rabbit persona. That tic became a durable meme across VTuber clips, TikTok edits and Discord soundboards, where short sassy reaction lines thrive. This version leans into that energy with profane, playful disbelief. Creators keep using it because it condenses shock, mockery and cuteness into three seconds, fitting fast meme pacing perfectly.
