Everyone who tries to define this is wrong.
Bffe does not stand for 'best friends for ever'.
Why you may ask, well forever is one word you fucking morons!!

The true definition of bffe is : 'Best Fucking Friends Ever'
Because there is no time limit. =
Dude! Rachel and Alyssa are total bffe's!!
Best Friends For Ever, One whos very special to you and who is very amazing.
"Your my BFFE" "Your my best friend for ever"

Best Friend For Ever

someone who has called you his/her Bffe considers you extremly close and among his inside group of friends

It can also be used in a sarcastic sense putting emphasis on how much they have a distaste for one another
Person no1:Fred Durst and Dj Lethal are Bffes

Person no2:Common knowledge

Person no1:Eminem hates Dj Lethal

Person no2:Man you kidding Eminem and Lethal are Bffes!
