B.A.F. 

Stands for Best A**hole Friend. It's for when someone can sometimes be a complete d*ck to you but still be irreplaceable and are a great friend. You can't hold a grudge for too long. They're not gonna hurt you, they're just really hilarious with a dark sense of humor. Will get you through the tough times and help you with ACTUAL a**holes.

Person 1: That friend sucks! He's a terrible person!
Person 2: Nah, you don't get it. They're my B.A.F.

B.A.F. 

Bomb Ass Friend. A friend who’s loyalty you don’t have to question or ever question that fact they are fake. They are as real as they get & the true definition of a ride or die. They will be there no matter what, so if you have a friend like that never take it for granted.

Man my friend is more then a ride or die they are a B.A.F.!
These are some reasons this friend is literally a B.A.F.
