facedog
Facedog is short for Facebook Dog. It's what you get when you can't turn off your Facebook chat. You're online all day, and the cool people leave you for someone who isn't a facedog.
My ex is a facedog. She was online 24/7 and still didn't get me.
That guy I liked was a facedog. He was online so much he got a second job.
My friend is a facedog. He got kicked out of the chat because he was online too much.
