1. to be a two-faced bitch
2. to act like a slut
then deny it or pretend to be oblivious to it
Helen: okay, that dress is way too slutty for you to wear out
Georgia: oh! you really think so? i didn't even notice how short it was...

Georgia: Helen was bitching about my outfit just because i'm skinnier than her
Sammy: don't pull an ashley, you do look like a slut.
