Resting bitch face (RBF) is a facial expression that unintentionally creates the impression that a person is angry, annoyed, irritated, or contemptuous, particularly when the individual is relaxed, or resting.[1][2] The concept has been studied by psychologists and may have psychological implications related to facial biases, gender stereotypes, human judgement and decision-making.[3][4][5] The concept has also been studied by scientists with information technology; using a type of facial recognition system, they found that the phenomenon is real and the condition is as common in males as in females, despite use of the gendered word bitch.[6]
