once and a while I see a white girl with some bump in the trunk

-- not too often but it helps if she has a real tight waist. I kinda agree with that other guy tho -- sure it's genetic, but the nicest bubble asses to me are still muscular... big flabby ass is too much for this white boy hehe...
funny thing about miami is the mall mannequins have big bubble asses hehe... umm yeah and all the shoppers too
