Reflecting upon things British today, having just completed my application for a British passport, I was pleased to be led by Lady Wit to this fine compiled List of British words not widely used in the United States over at Wikipedia (the best excuse to bunk off in a long time).
But some apparently want to merge this list, which focuses primarily, it seems, on vulgar and colorful phrases (Pawn’s favorite kind) with the more urbane and staid List of words having different meanings in British and American English. Pawn has just one word for that: Boring!
