Definition & Meaning of "fudge packer"in English

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

Fudge packer is a slang term that appeared in mid-20th-century North American English to describe a man known for engaging in anal sex. The term combines "fudge" as a crude euphemism for feces with "packer," implying the act of inserting or handling it, creating a vulgar reference to anal sexual activity. Historically, it was highly derogatory, used to mock, insult, or shame men for their sexual behavior. Today it remains offensive and vulgar, and using it in modern contexts is generally considered insulting and inappropriate.
