a girl or other who will add anyone on facebook but not know any one and gets gratification from her excessive catalogue of nobodies who also use facebook and may or may not have come into contact with the slut on one or more previous occasions - not necessarily classifying you as a friend.
Someone who has friends on facebook who doesn't socialize with them but merely teases you.
Fuck I hate facebook...
About 4.5 million people on facebook - for all those people who add me as friend and never talk to me - hug me - fuck me and think they are all that because they have a million fucking facebook fuckers on their friends list - you are a facebook slut
Someone who's life is facebook and never turns the computer off for a fear of a missed notice.

You are chating with your friend when; boom they are gone! No good bye, Mauh or kiss my ass. Nothing at all! At this point in time you are like WTF, wondering if there connection was bad or something happen to them? You sit there dazed and confused just to find out your "Friend" is an ass and does not feel like typing good bye. The term for this type of individual is Facebook douche bag...
