Exitiety

Exitiety is a play on the word anxiety. Best described as the stress you feel when going through the exit doors of a large department store - hoping that the teller has properly removed all security material from your purchase and therefore NOT setting off the alarm, causing a scene.

Dave: Dude, you got that movie at a great price... hey, why do you look ill?
Mike: Gee, I hope I don't set the door alarms off as we leave - I hate that!
Dave: You suffer from the worst case of exitiety I know!
