Pat-pat sounds grew into a small internet shorthand for comfort, popularised by anime edits and vtuber clips where a character receives gentle head pats as praise. The rhythmic tapping became a recognisable anime meme cue, showing up in wholesome compilations, cozy gaming streams and pet videos where words would feel like too much. Because the loop runs long enough to cover a full scene, editors reuse it as an emotional garnish rather than a punchline. Its staying power comes from simplicity: almost anyone recognises the gesture, so the sound translates across languages and fandoms without needing a caption.
