Otaku is a noun that refers to a young person who is obsessed with computers and similar interests to the detriment of their social skills.
A loan word from Japanese, otaku could be thought of as a synonym of ‘nerd.’ Here’s an example of it in use:
My son looks exactly like the same kind of Otaku as his father. He spends all day in school studying and learning, and all night studying and learning. Just like me, the only social skill he’s developed is talking about mathematic equations.
