A person who is self-centered, believes that he is right all the time. Likes to play mind games with girls, and is confused most of the time. Very emotional, and easily angered. Takes things the wrong way. Loves to skateboard, snowboard, longboard. Gets together with girls, has sex, then runs off to the next girl the next day.
"OH my god, he pulled a derek on me"

"Last night was a total derek."

"I'm sorry, I have to stop this, I'm being a total derek."

"I'm not being emo, I'm being Derek."

Most often a blonde. Usually talented with words and artistic. Guys with this name often are prone to collecting comic books and action figures. It is impressive if they are able to find a mate, even more so if they are able to produce offspring. Luckily they have a great sense of humor, are unselfish lovers (sometimes), and make good husbands.
I almost "dereked" when I considered rewatching all of the X-Men movies.

A Derek is a person who thinks he is right all the time. He has absolutely no friends. He tries to act and sound tough by yelling at everyone and trying to make them feel stupid, but if push comes to shove he will ALWAYS back down. He will never admit when he is wrong and will never apologize for something he has done, no matter how wrong that thing was. He will try to make himself seem like he is always right and play it off as nothing when he is proven wrong. He will even try to turn his own wrongness against the one who proves it. He is a pathetic excuse for a human being.
The Derek: "Shut up! You're wrong! You're stupid!"
You: *punch him*
The Derek: *hides in the corner and cries*
You: *leave*
The Derek: *complains about it behind your back*

"He acts like he knows everything."
"Oh, yeah. He's a total Derek."
