The 'pis, pis, pis' clip comes from user-generated soundboard culture rather than any known film, show or game, and it spread simply because it is instantly readable. Editors drop it over drip, leak and bathroom jokes where a longer water effect would drag, and its rhythm makes it easy to sync with quick visual gags. It sits naturally next to the classic fart sound on meme pages, and creators keep reusing it because the tiny repeated ticks sell the joke in under five seconds.
