Definition & Meaning of "manwhore"in English

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

"Manwhore" is a slang insult that appeared in English in the late 20th century, combining "man" with "whore" to describe a promiscuous man who has many casual sexual partners. The term borrows the negative moral judgment traditionally applied to women and applies it to men, emphasizing sexual recklessness or perceived immorality. It is used in informal, often mocking or hostile contexts, such as conversation, media, or online commentary, to criticize or ridicule sexual behavior. The term is derogatory and intended to insult; it is never neutral.
