Peko is the signature verbal tic of Usada Pekora, a rabbit-themed VTuber from Hololive who habitually ends sentences with peko, much like a character catchphrase. Fans clipped and shared her cheerful utterances, turning the short sound into a recognisable reaction across TikTok, YouTube edits and VTuber fan communities. Because it is so brief, it works as an audio sticker for delight, mischief or playful pride, and it remains popular as Pekora's audience continues to reuse her most distinctive vocal habit in memes.
