Definition & Meaning of "pole smoker"in English

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

Pole smoker is a slang term that appeared in mid-20th-century English to describe someone—usually a gay man—who performs oral sex on a man. The term comes from the crude metaphor of a "pole" representing the penis and "smoker" emphasizing oral activity. Historically, it was derogatory and vulgar, used to mock or insult someone based on sexual behavior rather than identity. Today it remains highly offensive and crude, and its use is generally limited to informal, sexualized, or aggressive contexts rather than polite or neutral conversation.
