Definition & Meaning of "ass jacker"in English

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

Ass jacker is a slang term that appeared in late 20th-century English, mainly in crude, gay, or prison-related contexts, to describe a person who enjoys anal sex. The term combines "ass" (anus) with "jacker," implying forceful or active participation, creating a deliberately vulgar and insulting image. Historically, it was derogatory, used to mock, shame, or demean someone for their sexual behavior. Today, it remains highly offensive and vulgar, and using it outside informal, sexualized, or subcultural contexts is likely to shock or insult.
