You guys are so shallow.
Fat girls are so sexy, so long as they're not rediculously large. There's lots to hug and snuggle to. They have such nice curves. A lot more comfier than any skinny girl can be. And they do not smell. Hell, they smell better than a lot of you guys.

OP, if you can't deal with her weight, move along. Let her find a guy that'll actually love her-- all of her. And to hell what the parents think, they're not dating her.
