A Facebooker who only ever comments on posts with the intention of calling into question the tastes or opinions of the original poster. Posts deliberately belittling or snide comments only likely to cause the originator offense or to reply in a defensive manner, provoking a 'Facespat'.

Cryptic posts in facebook that express a vague sentiment but do not provide any details, clearly designed to bait friends to ask follow-up questions.
A facebook wall post that could be considered facebait would be posts like "Today is the day!" or "Ugh, I am over it..." or "Now I know why I should stay home..." or "Hurt and disappointed..."

Posting to Facebook only to get a specific reaction from a specific person. Causes nearly all Friends to say, "Huh?", but one particular Friend to say, "Oo. I know what that's about." Not always negative. Not always positive.
Did you see that come across your News Feed?

Something's definitely up. He/she's Facebaiting somebody.

The act of posting on an acquaintance's wall after seeing them go idle in your friend list in order to bait them into getting back online. Usually targeted at women with whom the FaceBaiter is only loosely acquainted with the ultimate goal of starting a chat conversation without the appearance of trying.
Person: You talk to that girl from the party last weekend?

FaceBaiter: I was just about to but then she went offline. That bitch is never on!

Person: Dude, try FaceBaiting her. Tag her in a picture then you can mack all over that bitch when she gets back on. Get some!
