A gym regular, usually buff and tan, may or may not contain plastic. Can be found going full-tilt on the cardio machines, giving death glares to people not practicing gym etiquette, and silently mocking those she deems inferior. She may pay them a patronizing, backhanded compliment to complete her day. Tends to date a Chad or a Scott the Snot.
I forgot to wipe off the elliptical and this gym barbie almost decapitated me with her death glare.
