Definition & Meaning of "bum bandit"in English

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

Bum bandit is a slang term that appeared in mid–20th-century American English to describe a gay man in a sexualized and often demeaning way. The term combines "bum," a crude word for the anus, with "bandit," suggesting predatory or aggressive behavior, emphasizing sexual activity in a mocking or insulting manner. Historically, it was highly derogatory, used to shame, ridicule, or threaten gay men. Today, it remains offensive and vulgar, and its use is generally restricted to discussions of vintage slang or historical depictions of anti-gay rhetoric.
