Someone who finds your facebook account logged-in when you're not around and proceeds to change your status and/or profile information.
I think Mike may have been visited by a facebook fairy. His status says he can't come over to watch the game tonight because he's decided to adopt 20 cats and is knitting each of them a little pink sweater to "keep the kitty warm and pretty." LMAO!

A sleazeball loser that tries to lure women into a relationship through Facebook by convincing them he is a good guy.
OMG, that Bob turned out to be such a Facebook Fairy. He had Bonnie ready to marry him until she saw him working the drive through at McDonald's.
