オタク

Soundtrack: David Bowie's Oh! You Pretty Things
オタク (n) (col) geek; nerd; enthusiast
While "geek" or "nerd" in English carries some negative weight, オタク in Japanese does not have the same connotation. A better translation might be "connesieur." This is because seemingly EVERYONE here is some sort of オタク. Whether that be an Ahkihabara computer nerd (this is the first image that comes to mind when people use オタク), a Shibuya fashion nerd, a Harajuku anime nerd or a Music nerd. These are by no means mutually exclusive titles. I fully admit to being 2/4 of these.
