The phrase in the title is Dutch, with wanneer meaning when and poept meaning poops, giving the clip its toilet humor premise around a person named Ivy. Beyond that translation, the exact recording source and year are not documented in the listing, so it circulates mainly as a short user-shared soundboard clip rather than a confirmed movie quote. Its appeal online is its brevity and bluntness, making it easy to drop into chats, edits and reaction posts where a quick, crude fart joke is the whole point.
