when someone acts like they are your friend but they wouldn't know what real friendship meant if it bit them in the butt

Abby: Hey, Sally . . . let's hang out.
Sally: No, Abby, you are just a fake-a-friend and I don't want anything to do with you.

a fake friend

A fake friend is someone who doesn't really care about how you feel about yourself. Sadly most friends turn out to be fake friends and don't care about you. You should leave those fake friends right away and find someone real. I have had so many friends that I thought were real but in the end were just like the rest. In 5th grade I moved to a new school and became friends with someone I thought was so sweet then this year she just left me to go be friends with the popular girls but in the end they're just being fake friends to her now.

I can't believe she left me she was a fake friend
