A term used to describe people who are enamored with British TV, movies, music, and culture but do not live in or are in any way part of Britain. Crumpeteers will consume any form of British media for the sole reason that it was made in Britain. Many Crumpeteers think that this "appreciation" of British culture makes their taste in such things superior, but this is not necessarily a defining trait of Crumpeteers.
