You know you're addicted to derby when...
...all the NON-DERBY information your brain deals with in your everyday-life is turned into meaningful DERBY stuff...
And when you realize it, it's already too late. The only thing left to do is hook up with your addicted friends like a bunch of zombies on wheels trying to contaminate other people's brains to extend your flock pack. (and get more cool friends.) Because obviously, you can't be cool if you're not turned. QED.
