depends on your definition of fat
super-morbidly obese are still a no-no to most people
but of course there are the odd chubby-chasers around who will always find the bigger woman attractive and the non-fussy type who will sleep with any woman no matter what her size.
people like nicki minaj and kim k have just glamourized big bums and thick thighs so those who are not stick thin no longer have to feel insecure. not that they ever should have in the first place
