Nerd, as a stereotypical or archetypal designation, refers to somebody who is perceived to be of above-average intelligence and whose interests are not shared by mainstream society. Most people's interests are in the subjects of sports, music, fashion, food, etc., but nerds typically have interests that are more encyclopedic. The term is mostly widely used in the United States, but also has some currency in other English speaking countries such as Canada, Australia, and New Zealand.
