Annie: I saw my FBF in the hall way today and he winked at me. Yay!

Jamie: I can't believe Shakira is going out with Sam. She knew he was my FBF.

Facebook friend. Like BFF, but in the social network world. Requires official confirmation of friendship. Conversely, can be unfriended with a simple click of the mouse (no falling out needed).
Hey, why won't you add me as your FBF?

Friend by Force

Typical problem with people you just can't get rid off. They think you're their friend, while in fact you despise him/her. Can strangely enough occur over a longer period of time.

The reason is most likely that the person who is FBF with you is socially retarded.
(A) - Haha, what's up with your new friend?
(B) - Ahhh, i can't seem get him off my back. He's my FBF

FaceBook Friend(s)

A friend with whom you used to hang out or whom you used to see very often, but now your relationship is only limited to some occasional Facebook commenting on each others' photos, poking and whatnot. You do not even call these people on the phone anymore. your connection on Facebook is just to show them you're still friends, although you might not really be or want to see them.
-Wow! You and Jim still party? I saw his comment on your page the other day.
-no man, our situation has gone from BFF to FBF!
-I see.

Face book Freak- FBF is short for it. Some people are becoming myspace-like facebookers, and this is where the term comes from.
Betty was having a wall-to-wall With John 24/7.
So Betty's best friend told her "omg betty stop being a FBF!"

pronounced, EFF-BEE-EFF.

My FBF (Finance guy Boyfriend) works at a hedge fund. With a different financial institution collapsing daily, his trading positions had been blowing up and so was our relationship.
