There a lot of rude place names in the world. And helpfully, someone put them all on a map. Western Europe is full of them – the UK alone has Bell End, Shitterton, and at least two Twatts.
The US is blessed with a Spunky Puddle, a New Erection, and a Moist Cove.
Australia boasts Mount Fanny, Big Knob Waterhole, and Bumbang Island.
