Poop Napkin comes from the user-generated soundboard world rather than a film, television show or widely known meme, and there is no verified original scene behind the name. That low-profile origin is part of its appeal: short, downloadable joke clips circulate through meme pages, group chats and short-form edits, where an absurd title alone can make people curious enough to play it. It survives as a niche gross-out sound for creators who want a quick, juvenile punchline without borrowing a recognisable catchphrase or character voice.
