BFF
Best Friends Forever is the common term, But most of my crew use it as "Best Fuck Friend"

Alot of people don't have relationships instead have a variety of "friends with benefits"

Your most favorite friend with benefits is your Best Fuck Friend
They are good in bed.. But they are not my BFF. (Best Fuck Friend)

This girl is playing mind games on me. I may have to call the BFF and see if she can decipher the meaning of this text message.

BFF
Contrary to popular belief the acronym BFF does not mean best friends forever. The actual meaning behind this is "Built For Fuckin" and refers to any female that has features that make her good for one thing and one thing only...FUCKING!! Features such as a big round ass, big ass tits (perky or floppy), long luscious legs, big full lips, and sexy fuck me eyes are all traits that make one "BFF"
guy 1: "Damn dog, look at that bitch over there she's fine as wine"

guy 2: "Yeah, she's definitely BFF!!"

guy 1: "what's that?"

guy 2: "means she's built for one thing and one thing only...FUCKING"
