A person who has a Facebook account but rarely ever posts anything about themselves, but is constantly tagged in photos, makes comments, likes posts, has tons of wall posts from friends, thus showing they use the site on the regular basis, but simply read others posts to see what is going on in others lives only to say to you face to face "Oh yeah, I saw that on your Facebook"
Shannon: I can't stand Amy. she has a Facebook but never post anything about herself on Facebook, but when I see her she says "Oh yeah I saw that on Facebook"
Mike: Yeah she is a Facebook Sponge

Get the facebook pergatorymug. The act of recieving a chat from a person you do not wish to talk to, and then deciding to stay online (unlike offline race), but not do anything that they would see that would show them that you are online (e.g. states updates, comments, etc.). This nifty maneuver is done in hopes that the person chatting you will think that you left facebook up on your computer.
She won't stop chatting me; however, this time I used the facebook hiding tactic and it worked wonderfully.
