Definition & Meaning of "mythic bitch"in English

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

"Mythic bitch" is a slang insult that likely emerged in English in the late 20th or early 21st century, combining "mythic" (legendary or larger-than-life) with "bitch" to describe an extremely unpleasant, dominant, or notoriously nasty woman. The phrase exaggerates negative traits, framing them as almost legendary in scale. It is used in informal, often hostile, mocking, or humorous contexts, such as conversation, media, or online commentary, to emphasize extreme disdain. The term is clearly derogatory and intended to insult; it is never neutral.
