BBF 

Bad Best friend. Usually they are incredibly magnetic and good-looking but prone to ruthless behavior. They might be psycho, if you didn't feel such love towards them. Will defriend you, blacklist you, yell at you, and or give you the silent treatment whenever they decide you misbehaved in the slightest. BAD best friends are paranoid and toxic, and they use drama to their advantage better than anyone else you know. Related: BAG GIRL. BAD BOY.

if i weren’t doing this i’d be killing myself, or you, or your BBF Julie – you know she deserves it.
