The definition of having Whale Vagina Disorder is to have a small penis and lopsided balls and not get any ass. They are very homosexual and enjoy to eat there own shit.
This phrase stems from the film "Anchorman". During the seen where Ron is giving his new co-worker a tour of San Diego, he tells her that the city's name means "A Whale's Vagina" in German. This was such an obsurd suggestion that things to this level of proposterousness are therefore refered to as "Whale's Vagina"
