BFF

Butt Fucking Friends. BFF's are friends that routinely engage in anal sex with one another.

Me: "Have you seen Ted and Steve?"

other person: "They wanted some alone time they are BFF's"

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"

BFF

When applied to women, an annoying acronym meaning Best Friends Forever, but when applied to guys, has a slightly more condescending meaning, such as Butt-Fucking Fags, or Biggest Fucking Faeries, or --you get the idea

OMG, those fags are sooo BFF!
