Geek

The word geek is a slang term originally used to describe eccentric or non-mainstream people; in current use, the word typically connotes an expert or enthusiast obsessed with a hobby or intellectual pursuit. In the past, it had a generally pejorative meaning of a "peculiar person, especially one who is perceived to be overly intellectual, unfashionable, boring, or socially awkward".^[1] In the 21st century, it was reclaimed and used by many people, especially members of some fandoms, as a positive term.^[2][3][4]

Some use the term self-referentially without malice or as a source of pride,^[5] often referring simply to "someone who is interested in a subject (usually intellectual or complex) for its own sake".
