Definition & Meaning of "shitfucker"in English

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

"Shitfucker" is a crude slang term for a person who engages in anal intercourse. It appeared in late 20th-century English, primarily in informal, sexual, or insult-driven contexts. The term combines "shit," referencing the anus or feces, with "fucker," a vulgar term for someone who has sex, to create a blunt, derogatory label for someone participating in anal sex. It is used in insulting, joking, or sexualized speech and is highly vulgar and explicit, never neutral, and inappropriate in polite or formal conversation.
