BFBS 

An acronym short for bunchafuckinbullshit used to express one’s utmost rage and frustration usually said under one’s breath. Commonly used by moody teens when a parent doesn’t let them do something.

(Texting)

Teen 2: Damn that’s a bfbs

BFB's

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."
