yeah. . ."rappers" have to do that. . .sure.
there are lots of theories out there. most of them involve dna fluids and butt stuff. personally i lean towards the fact that butt stuff is anti-life. having shemale first ladies shows that no procreation happens in the white house. it is like an inverted vagina that brings death instead of life. classic saturnism. redirect the life force into death.
