How do you describe fanfiction to someone whose never heard of it before, and make it sound cool?

Every time I explain it I feel embarrassed, like I'm admitting that I still sleep with a teddybear or something childish like that.

But it's not a childish topic to me-- it's my hobby! And I take it seriously.

So how do you tell someone about it, without sounding stupid or crazy?

I want actual examples of dialogue suggestions, here. Tell me what to say.
