a lie. there is no such thing as having a BFF because eventually you will just stab each other in the back one too many times and it will be over forever.
the person you think is your best friend. if you're lucky enough to think you have one at the moment.

someone who is not worth crying over but you always do anyway

Person1: My so-called BFF just stole my guy/girl and now shes/hes pissed at me for no reason!

Person2: welcome to my world

BFF stands for Best Friend Forever, to me a BFF always has your back and is with you through everything. Having a best friend should be like having a brother or sister. Sure you'll have fights ,but you'll always make up. A best friend is someone you can't live without someone that fills a void in your life, someone who cares about you and who you care about. You shall have the strongest bonds that no one can sever. You may go in some of the best journeys in life together and have the best experiences while in each other's company. A BFF is a true friend you will have forever.
I known my BFF for 20 years and have had a lot of fantastic fun on vacations with her.

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)
