Facebook Effect 

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!"

Facebook Disease (FBD) 

When your profile picture doesn't look like you, but it looks worse than what you look like in real life. (Can also apply to myspace, but particularly facebook)

Guy:Have you seen my profile pic???
Girl:OMG its horrible. You have a serious case of Facebook Disease (FBD). You look way better in person.
Guy: Oh really? Thanks.

facebook taboo

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!

facebook taboo:

1: Waddappp dude!

2: Yoooo buddyyyyy *oh shit he knows I wrote on his wall*

Facebook Ammo 

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"

Facebook snob 

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.

facebook baiting

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.

(Next day)
It totally worked. We're going to 80's night at the bar this weekend.
