Resting Bitch Face
Published September 25, 2026 · Version 4.0.1
Resting Bitch Face is the term for an involuntary neutral facial expression that reads as angry, annoyed, or contemptuous even when the person feels nothing of the sort. First defined on Urban Dictionary in 2009 and pushed into wide circulation by a 2013 Funny Or Die parody PSA, it became the default shorthand for anyone whose default face looks mad.
Overview
Resting Bitch Face, also written as Bitchy Resting Face and shortened to RBF, describes a relaxed face that other people read as hostile1. The joke works because the mismatch is one directional: the person feels neutral or even happy on the inside, but strangers keep asking if they are angry, tired, or in a fight with somebody2. Urban Dictionary entries pin it to raised eyebrows, emotionless eyes, and a slightly hard mouth line, framing it as a look most common on women who look mean by default6.
The term works as both self identification and light insult, and most of the humor sits in the self identification side. Listicles about RBF read like symptom checklists, walking through the small daily indignities of being asked to smile more, being told to cheer up, or getting free guacamole at Chipotle because employees are afraid to charge you3. That confessional format is the reason RBF stuck around as a running joke rather than a one-off video, because anyone with the face can plug their own story into the template.
By the mid 2010s the label picked up a pseudo scientific frame too, thanks to a widely covered NYU study on how tiny resemblances to happy or angry expressions change perceived trustworthiness4. That gave writers a peg to treat RBF as a real perception problem instead of a punchline, even though the underlying science was about neutral faces in general, not a diagnosis5.
