The peko peko phrase is closely associated online with cute anime and VTuber culture, where short repeated catchphrases become shareable reaction clips. This version, labelled IV, circulates as a standalone soundboard clip rather than a full song or scene, which makes it easy to drop into edits. Its appeal comes from the instantly recognisable repetition and cheerful delivery, so creators reuse it for entrances, surprises and lighthearted moments across streams, short videos and meme compilations shared by anime and gaming communities online today.
