The 'Magnificently Rude Map Of World Place Names' is just that, a map detailing some really rude words — some more graphic than others — that has appeared online just in time for the festive season, should you want to shock your relatives.
It also depends on how filthy your relatives minds are — or indeed your own — as many of the words are pretty innocent really, like Phuket and Bangkok.
Other place names like 'Bum Bum Island' and 'Bobs Knob' are just funny.
According to the manufacturers of the map, Strumpshaw, Tincleton & Giggleswick, the maps "cause bouts of childish giggling" and could be "the best geography lesson you never had."
All the areas on the map are said to be "100 percent" real and it appears that the majority of knob related place names are in the southern hemisphere.
