A genetic disorder caused by the absence of the SRY gene in homo sapiens and other primates thus causing a pair of double x chromosomes to form. Henceforth these individuals develop a front bum. This disorder is not treatable and not having one when one should have one may lead to serious complications.
To quote Sir Mix A Lot "Baby got back," in the front. Therefore the bum looks as if it is attached not only to the back but to the front and the double x person looks the same from the back as the front thus creating a front bum.
