One who will contact an attractive male or female friend on face book within the first few weeks of the victim's relationship status change from "In A Relationship with..." to "Single" ... Classy Facebook Vultures will usually make first contact through the private messaging service as to avoid a high creepiness rating from the public while the less skilled will post on your wall. These wall posts usually have a reference to an inside joke from the past.
Whoa... Check it out! Anna-Lu just broke up with Chris! I bet if i'm the first person to post on her wall she'll wanna hang out and be all vulnerable and make out with me! -Male Facebook Vulture
O M G Todd and Becky just split up! I'm gonna write on Todd's wall so when he gets his hot sweaty dick online he'll know i care about him!! - Female Facebook Vulture

The feeling of déjà vu one often experiences upon meeting someone one has friended or Facebooked, but has never actually met in person.
Person A: "I feel like I've met you before."
Person B: "Yeah. I feel the same way."
Person A {struck by a strong realization}: "Oh! Do you have Facebook?"
Person B {struck with similar sense as Person A}: "Yes I do. That's where I know you from!"
Person A: "Dude! We totally just experienced the Facebook Effect!"
Person B: "Crazy!"
Person B: "Yeah. I feel the same way."

When a person rejects your friends request. leaves it in pending request mode OR adds you ,but blocks ALL their information and photos from you.
High school friend from many years ago added me ,didn't see any pictures on her profile but could see other "friends" talking about them on her wall.
Only a facebook snob would behave this way.

Any embarrassing, demoralizing or downright hideous picture of somebody saved on another friends camera that could be used against them for blackmail.
"Hey you better not take the last sprite or I'll put that picture of you after you spilled eggnog on your crotch at the Christmas party on facebook!"
"Damn, thats some pretty good facebook ammo"

Posting a status (or photo, or link, or anything, really) on Facebook with the sole purpose of baiting someone specific into commenting on it. Frequently used to initiate Facebook flirtation. Widely used as a tactic for such, but rarely acknowledged.
"I know Nick loves Bon Jovi, so I'm facebook baiting him by putting some "Livin on a Prayer" lyrics as my status.

When you write something on a friends facebook wall and then the next day you meet them in the hallway, both of you knowing about the said wall post, resulting in an awkward I know you know kinda thing. Because nobody says oh hey I wrote on your wall!
