Ok, everyone is bashing 'fat' women, and that's fine. Realize, however, that fat means different things to different people. There are no concrete limits to what is fat (obesity does). So if I were to say a girl was fat, of course she would be unattractive because she is fat in MY eyes.
So the question isn't 'why do guys like fat chicks' it's 'why do guys like chicks that I consider big?'. And as you can see, the answer is in the question. Leave the 'fat' people be. I'm pretty sure you guys wouldn't appreciate being talked about for your insecurity (whatever it may be)
PS, to extinguish the flames before they start, NO I'm not fat (170, 6'0)
NO I'm not a chubby chaser, but like a previous poster said, what's the point of this thread?
