1. When you have an itch you can't scratch, and it's killing you. So you wait and wait, looking forward to finally being able to scratch it. But then it goes away on its on, and you feel cheated.
Jack's crotch itched like crazy, but he was in church, so he couldn't scratch it. He waited until they started passing out the wine, then snuck out to the bathroom, but by the time he got there, the itch was gone. That's what's known as itch disappointment.
