A female who thinks she is intelligent when, in fact, she is very, very stupid; lives an incredibly easy life although she thinks she actually has a demanding schedule; thinks her 's#!t don't stink' both because of her rampant narcissism and because of her 'ultra cool' diet.
That woman spends most of her time at the gym which she considers to be as difficult as working a 9-5 job. She's such a gwyneth.
