What Book Did the Site Get Their Name From?

Tweet

I know that I read somewhere that the SuicideGirls.com website was named after a part in a Chuck Palahniuk (author of Fight Club) book. I just can't remember the book and I really want to read it. I hear that he's a wonderful author and I want to see if I think the name fits the site after reading the book. Any help would be appreciated!
