Definition & Meaning of "shit-stabber"in English

What is the origin of the term "shit-stabber" and how is it used?

Shit-stabber is a slang term that appeared in mid-20th-century English as a derogatory label for a male homosexual. The term comes from the idea of "stabbing" during anal sex, with "shit" referencing the anus, so the phrase literally describes someone who penetrates another man's anus. Historically, it was insulting and mocking, used to belittle gay men for their sexual behavior. Today it remains highly offensive, and its use is generally limited to informal, sexualized, or historical discussions of slang rather than polite or neutral conversation.
