A failure to see things as they really are, the failure to be open to new information. A human being that is unaware of their surroundings. The learned corruption of learning. Unfortunately for us, stupidity rules the world.
George W. Bush isn't stupid because of his inability to speak. Rather, George W. Bush is stupid because he refuses to learn about policies, history, & public speaking.

Dude and Bro have both been speaking with people infected with stupidity.
