She's probably the girl that surrounds her self with less attractive friends to make herself feel better. Asks them to eat out then only eats a handful of fries with her veggie burger and seltzer, exclaiming "omg I'm being so bad". Purposely takes them to the bar then approaches an attractive man with a larger friend at her side, making it seem as if they're the 'wingman'- unbeknownst to them being used as a crutch. Meanwhile she sneers in delight watching others engorge themselves with whatever fattening foods they please, even eggs them on to continue her escapade as the more attractive friend. When they ask why she thinks she's fat, she grabs her little fold of fat making it seem like a devastating amount. Then posts a pic on facebook drinking her skinny girl wine, all along knowing it's being used to be comfortable with her shortcomings.
