Although I've lived in Spain more than a decade, every time I go past the laundry detergent section in a supermarket, I giggle when I see boxes of Nuclear Bebé, a popular brand specially formulated (according to its manufacturer) to avoid irritating babies' skin. And it gets whites and colors nuclear-bright!
The lesson, of course, is that in other countries, words don't always mean the exact same thing: connotations don't travel well.
Every time I think of a nuclear baby, I think of something different and inappropriate.
