You flip plates over and take practice swings with them when you clear the table
when every piece of land you drive by would make the ultimate disc golf course.
when you think everyone should know what "hyzer" means.
....You have ever talked to your discs while they are in flight
When it's X-Mas time and you decorate your basket instead of a tree & place it on display in your living room!
When you start giving your best friends nicknames having to do with disc golf jargon.
You have to put more toys in your kids lap to balance the stroller because your disc bag hanging on the back keeps making it do wheelies.
when you use mini's for coasters.
You play at lunch time all the time ussually 2 or more times a week
You might be addicted to disc golf is your disc collection costs more than your car!
if you choose a location to BUILD YOUR HOUSE based on its proximity to a course!
have a couple hundred extra discs just in case
anytime you put anything in your hands you guess its stability
your two year old can throw both backhanded and forehanded

you have 260,000 miles on your ten year old car and you only live a mile from where you work...

if you know which of your ball caps is the least stable.
You wake up at 5am on a Saturday and don't even consider going back to sleep because TODAY YOU'RE GOING TO PLAY and you're wayyyy too excited about it!!!!
Your opinion changes from "It's great I don't have a yard with a lawn I have to mow." to "I sure wish I had a yard big enough to putt in."
You get upset at Christmas when no wrapped gifts appear to be round

Keep a spreadsheet of current inventory
Obtain two (at least) in same color and weight of each disc you regularly throw
