That doesn't mean what you think it means.

Poker face.
It does not mean "a face that looks like it was beat with a poker".
It does not mean "a face that should be beat with a poker".
It does not mean "scary face".
It does not mean "funny expression".
It does not mean "looks retarded".
It does not mean "has a birth defect".

I'll wait. Your final grade will be affected.

Bye for now.
