Jodie

She's a nice loyal friend at first, but when you'll get to know her more her true colors would shine. She'll start to forget about you and spend less time with you. She'll hang out with her other friends and leave you behind. She'll gossip to her other friends about you and give you dirty stares.

Girl: I used to be friends with her.
Other Girl: What happened?
Girl: She Left me behind and forgot about me. She's such a Jodie.
