Definition & Meaning of "cockweasel"in English

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

"Cockweasel" is a crude English slang term that appeared in the late 20th century to describe a sneaky, contemptible, or despicable person. It combines "cock," a vulgar insult implying rudeness or moral corruption, with "weasel," an animal long associated with slyness and deceit, creating a metaphor for someone both untrustworthy and objectionable. The term is used in informal, hostile, or humorous contexts, such as casual insults, online arguments, or banter among friends. It is highly derogatory and vulgar, intended to mock, belittle, or provoke.
