Similar to a God-complex, except only douchebagary ensues. Typically an only child, and often named Brandon(although they do not have to be named such), the subject says things to impress people that are unimpressive, and when called out on such, give you an angry, confused look.
Most are also spoiled, arrogant people who do not see their faults and will not accept the fact that they have faults; thinks everyone/everything is annoying, when in reality said person is the annoying one. Most friends are facades and utter insults behind the person's back, for good reasons too.
They also do not know how to properly talk with women, and will turn down women for idiotic reasons such as bad grades, or any lack of common sense. Stay away from anyone who has this complex, for only a failed friendship and your anger will follow.
Brandon, flexing; "Hey dude, I'm flexing. Aren't my muscles impeccable?"
Friend 1: "That's really unimpressive, especially since you are flexing. Why do you exist?"
Friend 2: "Indubitably; leave my premises immediately."
Friend 1: "What a classic example of The Brandon Complex."
