A fake friend who only knows you because you both liked a stupid game about cows.

I have 300 friends from Farmville. None of them are real.

I accepted a friend request from someone I don't know. Now I have to like their stupid post about their fish.

My best friend is a stranger I met on Facebook. We have nothing in common except a stupid app.
