This reaction sound comes from Usada Pekora, a popular Japanese VTuber from Hololive. Short Pekora voice clips spread widely in anime meme circles, on Discord, and in stream highlight edits because her voice is instantly recognizable and expressive. “Pardun” became a handy reaction for moments that need confusion mixed with playful disbelief. Its staying power comes from how short and flexible it is: creators can drop it into gaming clips, chat screenshots, and punchline edits without interrupting the pace.
