He's gonna be so pissed when he finds out about this falsebook! Fuck yeah!!! Wooooo!!!"

Facebook your ass

When a hurt, spiteful person posts something personal, private and intimate about another person where that person will in turn feel betrayed, embarrassed, hurt, or even criminally prosecuted.

She told John she wanted to be with him for the rest of her life, then she changed her mind. John didn't take too kindly with her decision. He told her, "Bitch, I'll Facebook your ass, so he Facebooked her ass and posted her brazenly bragging about all of her recent misdeeds

Facebook Fireman

This is a person who works for the Fire Department and at every opportunity this person is posting on Facebook about everything they have ever done while on duty. This is because they are not very good at the job, so they need all of the "pats on the back" from their other fake "friends" on Facebook.

"Dave is totally a Facebook Fireman."

Facebook Worth 

=((# of likes your Facebook post gets)/(# of Facebook friends)).

A higher Facebook Worth means your friends really care about you.

Facebook Is Dead To Me 

When a person gets to the point where they stop logging into Facebook because they are fed up with all of the pathetic and mundane posts by people who are trying to give the appearance their life is great, but in reality they’re unhappy and miserable.

Loser: Dude, why haven't I seen you on Facebook?

Non-Loser: Because I cannot stand all those fucking losers who are trying to pretend how happy they are. If they didn't have a forum to pretend they were happy and post pictures of their ugly kids,

they would probably be french kissing the barrel of a gun. Facebook is dead to me, you fucking bitch.

Facebook job 

Liking someone else's Facebook post, picture, or comment even if you don't. Like giving someone a handjob. Usually done so it seems you're a really good friend.

I think Sarah's going to unfriend me if I don't give her a Facebook job the next few days.
