One who passionately engages in one or more things to extreme levels. A commonly ascribed term to people in the field of computer programming, but one does not have to be in a technical field to be a geek. The only criteria is an intense level of interest in something, often to a highly specialized degree.

The term currently seems to be most used when referring to various fandoms. Whatever you do, never mention the Endor Holocaust to a group of Star Wars geeks. It will become amazingly convoluted.
I just finished creating a full-sized exact replica of the Mystery Machine from Scooby-Doo, complete with seat indentations based on the estimated weight of each member of Mystery Inc. I'm such a geek!
