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."
