1) A girl (or guy) who thinks they are a model, but in reality they are not. Usually they are just full-of-themselves, among other things!
2) A girl (or guy) who thinks they are a model, but really couldn't and shouldn't! They should take that money they were saving for Barbizon
and go buy a mirror!
3) Any girl (or guy) who isn't pretty...they just look that way!!
"There was always that one girl we knew back in high school. The spoiled only-child type who practically smothered herself in makeup and nail polish and was too busy to so much as give you the time of day. She thought she was going to be a model, but in reality she was just another barbizombie, trapped in the endless night-of-the-living-depressed."
