Get the Resting Bitch Face (RBF) mug.
An expression that is held by someone, typically (but by no means always) a woman. It is characterized by having a very slight scowl in the eyebrows, lips drawn in (sometimes occurred by sucking in the bottom lip), a pronounced tilt of the head, and a slight squinting of the eyes that would convey an expression of slight pain is discomfort. When performed properly, the sufferer should look to be perpetually constipated, and yet for some reason, utterly satisfied with being so. "Smug" is a common way to describe someone with a resting bitch face.

This expression is pronounced in its commonality, as in, it's the most common expression upon the sufferer's face. It is typically a signifier of someone who is arrogant, condescending, obnoxious or just generally bitchy. Commonly seen by journalists or other people commonly on TV.
I don't know how you can watch that show, the anchor has a massive resting bitch face. You'd think the higher ups would tell her to fix that.
