A dunny fail is any spectacularly embarrassing bathroom blunder — walking into the wrong public loo, getting locked in a festival porta-potty, or discovering there's no toilet paper at the worst possible moment. Beloved in Australian online circles for its vivid, self-deprecating energy, the term captures the universal humiliation of a toilet situation going catastrophically sideways. Whether it's a blocked cistern, a missing door latch, or a midnight stumble to an outdoor dunny, a dunny fail is the kind of story you never want to live but can't help telling.
Classic dunny fail — walked into the men's at the servo, slipped on the wet floor, and dropped my phone straight down the bowl.
