Similar to the Napoleon complex. A nerd complex is defined as the less attractive the nerd is to the opposite sex, the higher opinion the nerd holds of itself as to their capabilities in nerd culture (programming, compiling, quoting star wars, being good at video games, understanding science and technology).

The uglier or fatter the nerd, the more intelligent they insist they must be, in order to compensate for the fact that they are un-fuckable. Unable to face the fact that there is no direct correlation between ugly and genius and they are no more capable than a handsome nerd.

"There must be a reason why I'm like this"
"I'm absolutely disgusting and girls will never touch me, that's because god made me a super genius, the likes of Linus Torvalds or Stephen Hawking."

"Wow that guy's got a serious nerd complex, I write better code than this dork but girls still tug on my hammer here and there."
