RBFCU is a credit union based in San Antonio. Back around 2013, I noticed that RBF could stand for resting bitch face, and started spreading it the term. Today, most of the employees themselves have heard it. You're welcome, everybody!

The polar opposite of a female's bubbly smile. It's the grown-up version of the stern look a mom gives a child meaning 'I am displeased'. In the grown up version it's more like 'I am not amused'. Also, it can simply be a relaxation of the happy face a woman puts on for people who matter. This becomes more and more the case with greater age and less make-up.
