An extreme bitch/ 'friend' who will steal her 'friends' man, on her 'friends' birhtday, then try and be super nice to the 'friend' later, making herself feel good.
the worst part is, you can't even tell an ava you don't like her or don't want to talk to her or even that you'r mad at her because she always acts too fakely nice.
if you see an Ava, RUN!
don't invite her to your birthday party.
don't even approach an Ava, trust me.
Ava with Riley makes me sick!
1.) a best friend forever that is no longer your best friend
