Nerd [nɚd] is a term often bearing a derogatory connotation or stereotype, that refers to a person who passionately pursues intellectual activities, esoteric knowledge, or other obscure interests rather than engaging in more social or popular activities. Therefore, a nerd is often excluded from physical activity and considered a loner by peers, or will tend to associate with like-minded people. wikipedia.org is-a-nerd.com
