A friend who used to swear they're your bestie then one day ditches you at the drop of a hat to hang out with a completely new group who ironically become the entire world to them.

They will then act like you're an annoyance when you want to see them, but if they run into you, act like you're their long lost love and swear how you need to do more together. It never happens.
Girl 1: I just don't understand, last week she wanted to see me every day and now she's posting 500 pictures of herself and those other girls and won't talk to me

Girl 2: Forget her; she's a flea friend - bouncing from body to body.
