A person who doesn't have the nerve to confront a person in person, but instead verbalizes and creates drama and bullshit through Facebook.

She used her Facebook Balls to tell off her friend.

Facebook Balls 

Facebook balls refer to the harsh, rude things that people might say on Facebook that they wouldn't say in person.

Rob posted on Facebook that Larry's girlfriend is a total dog. He would have NEVER said that to his face. He's got some big FBB's (Facebook Balls). Then Larry posted back that he was gonna punch Rob in the face. The FBB's must be contagious.

When someone (usually a guy) won't talk to you to your face but they'll comment on your statuses/pictures, post on your wall, poke you, send you messages, "like" everything you do, and facebook chat you so much that your Facebook account exploes.

Facebook Chat blue balls 

when you look at your contacts on Facebook Chat, notice someone's online, click their name, then it tells you they're offline.
thus, you are left with "blue balls" because you thought you could get some Chat on and you're left wanting a conversation

Damn, thought he was online... Now I got Facebook Chat blue balls.
