BFB
"Before Facebook" - When someone asks for evidence of an event or connection to a person, but the event happened sometime before Facebook. The event or connection is then in a kind of limbo, as opposed to an event that is documented on Facebook and therefore more "real".

Related to: NOFB-DH - "Not on Facebook - Didn't Happen."
A Chat Transcript:

John: "I worked with (insert name of celebrity)."
Jane: "OMG! I love (celebrity)! Do you have any pics?"
John: "No. It was BFB, back in '96. I had a polaroid with him, but I lost it."
Jane: "Hmm... NOFB-DH.
John: ???
Jane: If it's not on FaceBook, it didn't happen. ;-)"

bfb
Acronym for 'better from behind'. Used to describe a visually challenged woman. Instead of adopting a missionary position or the girl on top, take the female from behind so one does not have to look at her face.
"Hey Nik, what was Angie like last night?"

"Oooh. A bit of a bfb, mate. We started off with her on top but Little Nikky was not not impressed - he retreated into his shell. Flipped her over and no probs. A lot better from behind."

Boobs From Behind. A fortunate combination of svelte torso and large endowment that allows the outside curves of a woman's breasts to be seen from a vantage point behind the woman.

BFB's are a very desirable trait.
"Bro, I can't wait for that chick in front of the line to pay and turn-around. Even her BFB's are awesome."
