The vaginarchy is the complex system of female beauty. Beautiful women are at the top of the vaginarchy, while ugly women are at the bottom. The vaginarchy can range from local, such as in a school or grade, or national/international, such as in the media or concerning celebrities. Any female knows that being in the vaginarchy sucks. It is destructive in nature - rejecting the system would be tantamount to social suicide, while rising to the top means accepting beliefs that are damaging and quite frankly, stupid. Either way, being a member of the vaginarchy sucks.
The stereotypical cheerleader is considered to be at the top of the vaginarchy - in tween movies, anyways.
The Bible of the Vaginarchy is any fashion magazine.
