As title mentions i don't really have many hobbies and i had a question on one of them, so in a small town of 30k what can i do to expand these?

Here's all i got for hobbies: Game enthusiast, PC builder, Semi-decent chef,

As for my question, how much of a turn off is it when you tell a lady your'e a nerd? I'm going to college for computer information systems so i thought it would kinda relate.
