shake of the head 

A slight shake of the head, meaning you screwed up so bad, that the other side can only shake their head. Or, other side is fed up with your shit.

Example 1:
Bob: DUDE! I ate a porcupine -- when it was still ALIVE!
Freddy: *Shake of the head*

Example 2:
Bob: Dude, I climbed Mt. Everest, pulled of my helmet, para-glided down, and landed on my head! And the only evidence I have is this small scratch on my elbow!
Freddy: *Shake of the head*

I can tell by the shape of your head 

A term used to suggest that someones whole life/personality can be determined merely by their appearance(The shape of their head). This is not alluding to the fact that archeologists actually can determine a lot about someone by the shape of their head; This can be done just by looking at them.

Look at yourself, I can tell by the shape of your head that you are a bitch; everyone can.
