Definition & Meaning of "megabitch"in English

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

"Megabitch" is a slang insult that likely emerged in English in the late 20th century, combining the intensifier "mega" with "bitch" to describe an extremely unpleasant, aggressive, or nasty woman. The term exaggerates negative traits, emphasizing severity, hostility, or dominance in behavior. It is used in informal, often hostile, mocking, or humorous contexts, such as conversation, media, or online commentary, to express strong disdain. The term is clearly derogatory and intended to insult; it is never neutral.
