Finland has a lot of intentionally rude place names, especially in the north. Places like "cunt pond" ("vittulampi"), "cockpile" ("kullirova"), "cuntwhistle bog" ("vitunviheltämänjänkä") etc. As to why this is, I've heard a number of theories. One is that people used to be less prudish and this kind of talk was much more commonplace back in the day. Also that the culture up north is more conducive to crude language.…
There are some good place names too, like "Shitterton", "Cockermouth", and "Bell End". Only Shitterton is intentional, though. It does literally mean "town near the place where you have a poo"
