I knew a dude who had a real sweet girlfriend, she could have been leaner but was certainly not fat.  I really liked her a lot (as a friend).  He kept cheating on her with fat chicks, then eventually dumped her because she didn't have big enough breasts.  They were at least D size on an average body, but all he wanted were saggy grocery bags of mashed potatoes stuck to her chest I guess.  The girls he cheated on her with were some of the dumbest trailer trash fatties I have ever met, I don't even know where he found them.
