Fake friend

Someone who uses you for their own personal gain
Hangs out with you only when they aren't around the "popular" people
Never apologize when their in the wrong

A backstabber

Shares your secrets with other people

Never listens

Ignores you until they need you

Hang with people you don't like/people who don't like you
Always put you down

Makes excuses for why they can't hang

You: "Hey do you want to hang out on the weekend"

Fake Friend: "Um no I can't I have to study for that math test"
You: "You said that last time

Fake Friend: "But its true this time"
