parker, you're an ass connoisseur extraordinaire.. but there's no way that her creamy, white, round ass, is gonna be 'flat' upon standing 
Find one of her standing. Until then, I stand by what I said. All chicas with ass, whether white, black, Latin when bent over have more ass horizontally---because the ass fat has to be evenly distributed to the side. Now black and Latin chicks with black in them, their ass went bent over has a semi circle look to it. Basically, in a bent over position like the said blonde chick, one must imagine the girl either sitting down in a chair or squatting. And in the splayed leg position she is in, and if she were wearing jeans, I would definitely say she got a flat ass, she would not fit in Apple Bottom Jeans.
But she would get it like no other...
