Marble Brain 

A close reference to "Waterhead" or "Smoothbrain". A "Marble Brain" is typically a just a stupid person with cognitive skills of elementary school kid. Every thought or response is simple & incoherent. Furthermore, it is believed a "Marble Brain" loses a single marble trying to repsond until all their marbles are gone. This is followed by rambling & annoying trailing sentences.

Wow, the retard with a hockey helmet and a bail bonds shirt looks like a Marble Brain.

DK Brain 

Perfectly imperfect. The class for the stupidest man alive. If you don't want to have to provide utility and have to think before a button is pressed this class is not for you. If you enjoy slowing multiple enemies and relying on multiple minute cooldowns to kill something that you cannot possibly fuck up no matter how dumb you are this may be your class.

Damn this guy has a bad cause of DK Brain, what a fucktard.
