B.F.F.

Normally used to mean "best friends forever", but occasionally used to mean "butt fucking fags" as a humorous double entendre.
1. "You're a great friend Sara. We're B.F.F.'s." (sincere)

2. "Look at those B.F.F.'s over there ... snicker." (second meaning)

B.F.F.

Commonly used as Best Friends Forever, but among your overweight friends you can use it as Big Fat Fucks.
John: Hey, wanna go to White Castle?

B.F.F.

Brain fart factor. A measurement of how much obvious information you forget when you take a test. Those with a B.F.F. of .1 forget 10% of the obvious. Those with a B.F.F. of .2 forget 20%, etc.
I only studied half the material and I have a .5 B.F.F. I'm only gonna get a 25% on the test. I'm screwed.
