PS: the Romanian verb "a face" is in the first person "(eu) fac". This fac is pronounced exactly like the English word "fuck" ... In Swedish we have the word "fack" which also is pronounced like "fuck", but means safety deposit box (the bank) or worker’s union. So if you hear Romanians and Swedes say this to you they are not trying to be deliberately rude, they’re just saying “I do” and “safety deposit box/union”!
I already knew the Swedish one. I think it was here on WR where I read a story about two elderly ladies who went to London and asked in a hotel, "How much do you want for a fuck/fack?"
