What is a person obsessed with a hobby or intellectual pursuit called?

What even is this question??

I enjoy this game and usually your questions are spot on but this one was ridiculous.

I suppose this is one that depends on the context in which it's used. To be called a "computer geek", is not a great insult. On the other hand, to be called some other type of "geek", might be considerably less flattering.

All that explanation and no mention of Star Track ?

Well, I’m not the first to object to this question.

a geek is a comic book/scifi nerd

The answer should be otaku

A geek is a person who bites the heads off chickens in a carnival or circus.

I thought it was an aficionado lol

swish, you're correct and I saw it happen once when a kid

Player #mamajord, Are you by any chance that chicken!
