Facebook Tease 

Refers to a member of Facebook that flirts with other members of Facebook with no intention of ever following through on said flirtation.

The Facebook tease will also upload dated photos that completely exagerate their appearence, so if they ever do follow through with their flirtations, the other party will be thoroughly disappointed.

I know that chick sounds sexy, but she's a complete Facebook Tease.

Facebook Slighting 

When someone who is supposedly a friend almost immediately deletes any posts by you or gifts from you on Facebook, even if they are private. It indicates that they are only willing to be your friend if nobody else knows.

Erin: What's Louie's problem these days?

Jack: Oh- Marsha is constantly Facebook slighting him.

Facebook-worn

A phenomenon which makes people think you wear a particular item of clothing all the time because you are tagged wearing it a lot.

This is even if the photos were from several separate nights which were months apart but they were the only photos you were tagged in.

I was going to wear that black t-shirt tonight, but i'm wearing it in my recent Facebook photos, so it's a bit Facebook-worn.

Facebook Social Distortion Disorder (FSDD) 

A social disorder that makes it possible for your close family and friends to forget about you if u are not currently active on facebook. Sufferers will actually stop emailing and texting you if you're not constantly reminding them of your existance via facebook updates. If you don't exist on facebook, you don't exist to them at all.

I deleted my pics on facebook, and no one called me for a month! I didn't even get invited to my own class reunion. Wow, I didnt know the class of 2000 had Facebook Social Distortion Disorder (FSDD).

Facebook Official 

When an event has happened and it only really counts if it has been put on Facebook for everyone to see.

So I heard that Jess has a boyfriend now, I'm not sure though because it hasn't been made Facebook Official yet.
