Definition & Meaning of "cunt sucker"in English

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

Cunt sucker is a slang term that appeared in mid-20th-century English as a vulgar label for a lesbian woman. The term combines a crude word for female genitalia with "sucker," emphasizing oral sexual activity. Historically, it was derogatory and insulting, used to mock or demean women for their sexuality. Today it remains extremely offensive and is generally limited to crude humor, sexualized contexts, or discussions of historical slang; it is not appropriate in polite or neutral conversation.
