I work with a guy who talks about f'n fat girls almost everday. It is comical, he is so proud of it. He said he doesn't know why but he just doesn't think slim girls are attractive. We were out on an install once and there was one of the hottest girls I've ever seen, and all he could talk about was this fat, ugly skank that was there.
Fatty's are different and put out easy because they go out like we do, as hunters. It's like asking why do guys put out easy. They hunt for cauk like a true predator hunts for prey. Just like how a wild animal will stalk wounded prey...fat girls look for guys who have had too much to drink and all judgement and decision making abilties have vanished and then in the wee hours of the night they attack. I know many on this site have fallen victim at least once. I would say they are the same as guys but they are not. They are at the top of the sex food chain because nothing hunts them.
