someone who uses facebook but is looking at other peoples profiles, going through their pix, reading their messages. It's a little like stalking.
you - "what are u doing?"
me - "looking at my boyfriends ex girlfriends profile on facebook, according to her mini feed shes missing her ex"
you - "your such a facebook creeper"
me - "yea I know"

Usually a picture that is taken, reviewed, and agreed upon as being Facebook worthy. Often accompanied with words like totally, clearly, or sooo not.
"That picture is totally Facebook material."
"Ugh, I look like a bug in that pic... that is definitely not Facebook material."
