There a lot of rude city and town names in the world. Someone used up his time to 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.
Meanwhile, New Zealand is full of Knobs.
Even Antarctica gets in on the action.
