Does she really mean it or is it a joke?

[Eric]

I was looking up my facebook wall and then I see how girl was posting "he's so ugly when he eats at our lunch table" Then the other girl says that I always eat like a slob. And "omfg he needs to get away from us. He always a sly little Asian". Is this girl actually serious where she wants me to not be near her. Or is it where she's joking/kidding.

Extra details:
1. Doesn't really start up conversations with me I do it.
2. Her friend doesn't like me that much
3. We are just 'friends'
4. Asked if I could sit at her lunch table the whole semester and said yes.
5. Her friend thinks I'm lame.
