A phenomenon in which the resting face lacks animation and appears to look bitchy at all times, thus leading people to believe a person must be upset, a snob or a bitch.
Comments people with resting bitchface are eternally plagued by:
"What's wrong? Are you okay?"
"Are you mad?/Sad/Depressed?"
"You know...Before I got to know you personally I thought you would be a snobby bitch."
"I bet you're the type of girl who has a major temper when you get mad."
Resting Dick Face (RDF) is the male equivalent of RBF. Yes we look like dicks that hate everybody as we face rest, but we actually are nice people (mostly).
Woman - "What's wrong with your friend?"
Man - "Jim? He's just got resting dick face, he's actually enjoying being here."
