1. When a typical female (in most cases a promiscuous slut whore bitch) who was born with (some) looks, tries to "be all that she can be" or more than she was ever meant to be, by participating in beauty pageants in hopes of becoming some sorry excuse for a star despite having zero talent whatsoever.
2. An emerging or established starlet who is known for sleeping her way to the top rather than possessing actual talent in the entertainment industry.
Man 1: Man did you see who won the starwhore pageant this year? Man 2: I recognize her, if it ain't our own little high school slut, man I nutted over that bitch's face when she was only 15 and I was her math tutor! Fuck me now she's a starwhore!
