I live in an area with high immigration where 75% of kids at DC1's school are bilingual in a particular minority language. When I introduced newborn DC2 to our neighbours with her standard English name, they were a bit 
and 
and said "you know what that means in XXX language, don't you"? Oh shit I thought, I've called her the XXX equivalent of dogbreath or something. Turns out it's not that bad, it just means daytime, but it got me thinking, it would be interesting to hear what other names have, erm, unfortunate meanings in other languages. Like my poor French friend Fanny.
