Idiotic (and not really insulting) slur against people with red hair, employed in Britain, Canada, and other heavily Anglocentric cultures. Often rhymed with equally
nonsensical and
stupid words like "minger" and "whinger." Not really used in America (where we
have the balls to LIKE redheads), except by a handful of people who think that adopting British-style racism makes them sophistcated and cool.
