As seen on an episode of 30 rock.

BFF stands for "butt fucking festival"
Jack: Look we got BFF bracelets

Liz: you guys are best friends forever?

Jack: thats not what that stands for..

*whispers in Liz's ear*

Liz: Why would you celebrate that!

best friends forever...an interjection that is used to end an email in case one of the corresponding parties dies in a car crash in a ditch before the two see each other again.
Okay...I´ll talk to you later...bff!

for some reson BFF is the acronym for Best Friends Forever.
but don't it look like 'Best Fucking Friend'? i think so.

BFF = Best Fucking Friend

B = best
F = fucking
F = friend
"dude, you rock! you're the bff (best fucking friend) i've ever had!!!"

Guy-You know the girl that asked if you had a sister is her bff right?
Other guy- Yea, she was trying to play me, but I knew that was my sister's best friend. She wanted to pretend to be my friend.
Guy- Damn that's fucked up man.
