I've always claimed, for comic effect, that my verbal outbursts of obscenities whenever I'm screwed over by the NHS (or by anyone else, for that matter) are signs of me having Tourette's.
Well, I stand corrected. It is Tourette's-related but there's a specific term for it... Coprolalia.
It's from the Greek and, in layman's terms, it means... "talking shit".
