nd the rather rude "You twat!" - which, interestingly enough, is pronounced differently
in the UK - where they make it rhyme with "cat" - from how it is pronounced in (scary
loaded word coming up) the colonies, where it rhymes with "what."

Dear MG: This word interests me, because I think it is related to the cross-wise plank in a skiff, which is called a "thwart", on which you rest your butt. It is also used to refer to the female pudenda. I have seen a quote in that sense dating from about 1200. And I have only heard it pronounced like 'not'.
