brain 

To throw an object, usually a rock or coke can, at someone's head.

The steps of the Brain are simple:
Step 1 - Put your hands palms facing each other and completely flat
Step 2 - Stick them inside another person's anus
Step 3 - With your hand in the same position form them both into fists
Step 4 - Ram your "brain" back and forth inside of the person for optimal pleasure

Brain 

The thing that controls you and has a mind of its own (no pun intended). It can mess with you and just make you say dumb things in front of hot girls.

Jim: Hey wassup pretty gal.
Hot girl: What?!
