Douche Bags are people who are very disrespectful and somehow manage to think they are "it" when in actuality they are not. They are the bottom of the social chain with their low grooming standards and inconsiderate attitudes and yet they think that they are the upper crust of society walking around with an undeserved sense of accomplishment. Douche Bag is a great term for anyone who is arrogant. The amount of success for a person does not matter one way or another as long as that person is considerate of other people and not so ignorant.
Douche Bag: I am so much cooler than those people who work at Starbucks with my construction job. I decided I want to grow out my goatee another foot while I get 50 more piercings while I spend 500 more dollars to tatoo my entire back. I'm going to go back to my trailer and add another beer bottle to my 300 other ones on the counter. Yeah I'm better than you college students! You're worthless! I'm bad ass!
