This clip is associated online with the repeated "peko" verbal tic used by Usada Pekora, a rabbit-themed Japanese VTuber from Hololive. Short cuts of her saying it spread through fan edits, compilations and meme reposts on YouTube, TikTok and Discord. The sound stays popular because it is instantly recognizable to anime and VTuber audiences, while the quick up-and-down cadence also works as a reaction punchline even for viewers who only know it as a meme audio.
