Used to discribe a photograph, video, or real-life scenario that depicts two or more fat girls having a good time. The same situations or media produced or acted by skinny girls would be seen as cute and fun and their good-time would be envied by all.

In the case of fat girls, their attempts to copy the good times of skinny girls are intepreted as "desperate" and hilariously sad.

Evidence of fat girls having fun can often be found in facebook or myspace photoalbums taken in front of bathroom mirrors, before high school dances, or by apple photobooth. Worst of course, are the photos taken by the beach.

Throwing up gang signs or making seductive kissy faces are quite common.

The desperate way of wishing for something that will not happen because the wisher does not have enough self-discipline.
Betty: Oh, Carlene! I really hope that Graham calls me! He's just so dreamy!
Carlene: Betty! Get real! He's from the good part of town. You truly wish like a fat girl!
