A disease that is plaguing this great nation. It is when guys think their team is better than it could ever be. They suffer from a case of the Moroses. Half moron, half medical word. Moroses.
Dylan was suffering from a severe case of the moroses today. His Giants lost to the Saints yesterday and he's still bragging.
