Definition & Meaning of "shitweasel"in English

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

"Shitweasel" is a slang term used to describe a person regarded as sleazy, contemptible, or untrustworthy. It likely emerged in English in the 20th century as a colorful insult, combining "shit" (symbolizing filth or moral corruption) with "weasel" (an animal long associated with cunning, deceit, and slipperiness) to convey both disgust and distrust. The term is informal, strongly derogatory, and used in hostile, mocking, or contemptuous contexts to attack someone's character. It is never neutral.
