Nerd

In general, a nerd is a social outcast in some way shape or form. However nerds can also be socially adjusted and may be popular. In most cases nerds are not very happy people, because despite their levels of popularity, they usually don't have much of a life. While it's perceived that what determines nerdiness is what the person is into, it goes deeper than that. Nerds are usually diagnosed with some type of minor mental disorder (ADHD, Aspergers) and as a result act in a way that many people find strange and may tease them because of it. Also, nostalgia and escapism are two very important things to a nerd. Nostalgia because childhood is always better than adolescence, and this rings especially true for nerds-and escapism for obvious reasons. Common traits for nerds are intelligence, low self-esteem, shyness, sexual frustration and yes, narcissism. Nerd pride, while a healthy thing can also be dangerous. Many nerds become bitter towards society and grow massive egos, which only makes more people hate them. While many nerds are mature and intelligent, many others (despite stereotypes) are ironically just as petty and small-minded as many of their tormentors. Then of course on a smaller level, nerds are defined for their interests. Stereotypically, video games, books (especially of the comic variety), and anime, as well as many other things.
