addict

Someone who is obsessed with something. They would do almost anything to get at whatever they are addicted to. It can be very unhealthy and become extremely serious.
Bob: hey you've been on the computer for quite a while. Maybe it's time to give it a break?

Cassie: NO WAY. I'm on facebook, can't you see I'm extremely busy creeping on people?!

Bob: OK Cassie, I didn't want to do this but were going to have to have an intervention. The first step is admitting you have a problem and that is: you are a facebook addict.
