A douchebag is characterized by many different qualities so this will be a lengthy definition.
Whether or not someone is a douchebag, can often be determined by a combination of their attitude, attire, and lifestyle.
First we'll start with a basic definition. Douchebags at their core are pricks who have massive egos and think they have the right to treat other people like shit, they think they own the world. They somehow have been deluded into thinking they are extremely attractive, tough, and that everyone likes them, which is far from the case. They are often white teenagers, but can be found in other age groups, and occasionally other races.

Let's look at atire.

Douchebags tend to flock to places such as Abercrombie and Fitch, or Lacostalot, excuse me, Lacoste. They often wear cock eyed or reversed flatbills of a baseball team that is located no where near where they live, usually the Yankees or Red Sox. You may see excessive jewelry also, such as massive stud earrings, I'm not talking just little earrings, massive earrings. They wear pre-ripped up jeans, I believe they call it stressed in places such as Abercrombie and Hollister. More often than not they have short hair, often spiked up with some sort of product. It really isn't that hard to find them, a good portion of teens today are doucehbags, they all look the same and they all look like faggots.

More than just the way one looks characterizes a douchebag though. They are huge pricks, and just have an aura of egotism around them. Whenever they look at someone who doesn't look like them, you can see the disdain in their eyes, they just hate them for no apparent reason. They have shitty attitudes, they act like pussies when they don't get there way are have to do something that isn't "cool" enough for them. They are very elitist and don't understand what it means to be laid back and accepting. They love talking shit, but can't back it up, I once recieved a death threat via text from a douchebag, I think he works at Abercrombie...

They treat women like shit, and the only women who go for them are shallow, easy, and have no self respect. Once you get to college they don't even get these women, beause ithey aren't needed, because they just try to get women really drunk so they can sleep with them. Another thing they do is search for extremely easy girls in the area on Myspace, although girls who fall for this deserve their fate. So ladies, if your guy has any of the qualities in this definition, you should probably really think about what you're doing.

The most important thing to remember when dealing with a douchebag is that, everyone else likes you more than him, and he's a pussy. So feel free to either kick his ass, verbally destroy him since he's probably a dumbass, or just ignore him. One good way to react if a douchebag is talking shit to you is to laugh at him. They'll be confused when they realized they didn't intimidate you, or even make you angry. This confusion will make them angry, and they won't know what to do. Instant win.

Just try not to be a douche.

Someone who has surpassed the levels of jerk and asshole, however not yet reached fucker or motherfucker. Not to be confuzed with douche.

An individual who has an over-inflated sense of self worth, compounded by a low level of intellegence, behaving ridiculously in front of colleagues with no sense of how moronic he appears.

A person with a shitty personality that needs to "take themself the fuck down" or "go home and get their fucking shine box." A douchebag usually assumes the form of a hair-gelling pretty-boy but can also be described as an overzealous, pompous, or vexatious asshole that most people wish were killed with a Mortal Kombat fatality.

The term "douchebag" generally refers to a male with a certain combination of obnoxious characteristics related to attitude, social ineptitude, public behavior, or outward presentation.

Though the common douchebag thinks he is accepted by the people around him, most of his peers dislike him. He has an inflated sense of self-worth, compounded by a lack of social grace and self-awareness. He behaves inappropriately in public, yet is completely ignorant to how pathetic he appears to others.

He often talks about how cool, successful, and popular he is, yet never catches on to the fact that he comes across as a total loser. Nevertheless, he firmly believes that he is the smartest, most desirable, and most charming person in the room... and will try to bad-rep anyone who would threaten to expose this facade.

He fancies himself a ladies’ man, yet tends to be a joke to all but the most naive of women. He tries to portray himself as part of the in-crowd (a fashionista, an upwardly mobile professional, the life of the party, etc.) but only succeeds in his own mind.

To everyone else, he is an annoying and arrogant phony who comes across as a wannabe overcompensating for his insecurities. He tries to appear like the center of whatever group will tolerate him, but in reality, he is just a tag-along who mooches drinks, women, contacts, social standing, and other benefits from the group... while contributing nothing.

A-list ego; D-list status.

What used to be accurate on this site, was replaced by a bunch of people who defined it because they really had no clue what it meant. A douchebag is a pretentious, sugar coated prick, but with emphasis on pretentious and sugar coated. It's not an adjective for an asshole, because assholes call other people douchebags, and assholes are more often than not proud of being assholes.

An individual who has an over-inflated sense of self worth, compounded by a low level of intellegence, behaving ridiculously in front of colleagues with no sense of how moronic he appears.
