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.

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!

The act of marking one's significant other on Facebook through cute, flirty comments and a plethora of likes, so as to make evident to others that there is a relationship in existence. Akin to a dog peeing on a tree, this is a person fairy dusting another.

Synonymous with Twitter Glitter, the same technique but used on Twitter.

A riff on the "glitter" technique some women use to physically mark men with glitter (wear glittery cosmetics, hug/kiss, it rubs off on him, and if he shows up to another woman--she knows there's another woman already in his life).
Jim has really Facebook Fairy Dusted Kelly in the last few weeks by commenting on and liking every single post she's made.
