Someone (usually a woman) who is given the highest accolade of seven dwarfs when being judged on attractiveness. The word derives from the tale of '
Snow White and the Seven Dwarfs' in which
Snow White befriends seven dwarfs but is made ill by a poison red apple. Therefore if it is later discovered that a
snow white has a major flaw (or weakness), the flaw is termed a red apple (poison red apple or poison apple).
