When you take the monkey brain you form by stretching your skin tightly around your ball sack tightening the skin till it resembles a minature brain and placing it out the top of your waist line so that it resides on your belt buckle
To create a Monkey Brain Belt Buckle. Place your brain to belt buckle position and then call upon a near by friend to bear witness to it.
