A word, which describes someone who has numerous personality defects, which make them undesirable and unfit for social interaction. These people are repulsive and are likened to a douche, a device used to clean the most unsightly areas of the human body--the asshole and the pussy, which, not by coincidence, are words often used interchangeably with the world "douche" to describe such a person. Characteristics of a douche, include but are not limited to being cocky, pompous, self-centered, selfish, mean-spirited, and of course, being an asshole or a pussy, as mentioned earlier.
That guy in the Camero is such a douche, I can smell his Drakkar even with my windows rolled up. His own mother must hate him. What an asshole/pussy.
