Definition & Meaning of "bitchface"in English

What is the origin of the term "bitchface" and how is it used?

"Bitchface" is a slang term that appeared in English in the early 2000s, combining "bitch" (implying unpleasantness or hostility) with "face" to describe someone whose facial expression appears constantly angry, annoyed, or unapproachable. It is most often applied to women, though it can describe anyone, and emphasizes a perceived permanent scowl or resting angry look. The term is used in informal speech, social commentary, and online discussions about appearance or demeanor. It is derogatory, often mocking or critical, and carries sexist overtones when applied to women, though it can also be used humorously in casual contexts.
