The word "geek" refers to a person who is very knowledgeable or enthusiastic about a specific subject, especially in technology, science, or pop culture. It often implies a deep passion or specialized knowledge, sometimes to the point of being socially awkward or eccentric. While the term was once used negatively, it is now often embraced in a positive light by those who identify with it.
The term "geek" has its roots in the early 20th century, originally used to describe a sideshow performer, particularly one who performed bizarre acts. It likely derives from the word "geck," which was a Scottish term meaning "to bite" or "to cheat," and later evolved to refer to someone who is considered odd or eccentric.
