When you act like a total nutcase about something just because you're obsessed with it.
I had to wash my hands 17 times because I thought I touched a doorknob that was touched by a doorknob that touched a dog that touched a sidewalk.
My mom thinks I'm a freak because I line up my socks in order before I can leave the house.
I had to reorganize my fridge three times just to make sure the cheese was in the right spot.
