Term used to describe the angry-looking facial expression that
one instinctively makes when s/he is resting, zoned out, or not actively engaged in a conversation. Someone with an angry resting
face may be unfairly perceived as
cold or aloof. An effective remedy for an ARF is to learn to "smile with your eyes."
"That
Alison looks like such a bitch."
"Nah dude, she just has an ARF (
Angry Resting
Face). Girl's gotta work on that."
