n. an asian slut with way too much makeup on (like those who work at M.A.C. Cosmetics) to the point where you cannot see the relevance between them and their respective family members.
examples of how to identify a M.A.C. bitch:
1. see if you can see the individual hairs of her eyebrows
2. see if you can tell what her natural skin color is
3. see if her makeup always matches her outfit, down to her wetseal thong
M.A.C. bitches who go to the predominantly asian clubs every weekend, who usually have 'ties' with the bouncers.
