Barney says your docuhebag
In other words a douchebag
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.
A douchebag will often bring his SLR to bars to take pictures of good looking girls (with or without their permission), perhaps pretending to be a professional photographer. He will try to be in as many photos as possible (often posing with his arms around total strangers or his friends’ girlfriends) and post them on his personal websites in an effort to convince his online community that he is a bigtime bar-star. He is also likely to boast about his "conquests" (usually exaggerated or fabricated), failing to realize that this only serves to impress fellow douchebags.
