This tombstone is source of endless (sorry...) joy for Poles. I don't think KURWA DUPA requires translation for anyone speaking Slavic languages - or living in UK. These are... bad words.
The legend is that a Polish mercenary in Africa was dying in pain and whispered "kurwa, dupa", but the nurse was asking about his name. So his name for carved in stone forever.
Then, nerds from odkrywca.pl found out it's actually a name in Suahili, and this grave is in Kenia 🇰🇪
