The attitude and overall demeanor developed by a man, while watching an episode of HBO's Entourage.
Usually consists of delusions of grandeur, of invincibility, and a loss of perspective of the truly important things in life WHICH MONEY WILL NOT BUY!!!
USE EXTREME CAUTION if a sole female, watching this show in the company of two or more males; as this condition has a tendency to grow exponentially the higher the testosterone count in the room.
May cause irreversible damage if not countered with large doses of Estrogen IMMEDIATELY!!!!......
