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.
