When you check your Blackberry constantly because you swear the "Notification" light was flashing, only to learn that it wasn't.
Jake: Damn, why are you always checking your Blackberry at work?

Derek: I don't know. Sometimes, I swear the light is flashing. But most times, it is not. I definitely have Blackberry dementia.

Jake: Why don't you just wait and see if the light flashes again?

Derek: Why? Fuck you! That's why.
