RBF=Resting Bitch Face. That means to always look either serious, mean, rude or bored when you’re face is neutral, or resting. But this doesn’t mean that people with RBF’s are actually mean, it’s just how their face was made :-D.

Alexandra always has a RBF on display, causing people to shy away from her.
