Geek is a slang term for someone who is really intelligent or knowledgeable, especially about a particular topic. If you're a Star Trek geek, you know absolutely everything about the famous television show and its spin-offs. Live long and prosper!

Intelligence does more good than stupidity, so the negative way people sometimes use the term geek seems unfair. So if you're a geek when it comes to computers, chess, books, sports statistics, or just about anything — be proud! The Scottish root word geck translates as “fool,” and many famous geeks were called fools before their ideas changed the world. Remember, today’s geek is tomorrow’s billionaire.
