Somebody that is addicted to facebook. Usually has an application for it on their phone so that they can post their whole day on their wall.
dude 1: Have you seen Jenny's new phone?

dude 2: Yeah. Ever since she got it, she's become a face addict. She replies to all my post even though we work different 12hr shifts at work.
