Definition & Meaning of "assbag"in English

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

Assbag is a slang term that appeared in mid-20th-century English to describe a person regarded as worthless, contemptible, or obnoxious. The term combines "ass" with "bag" to create a vivid insult, implying someone is full of unpleasantness or of no value. Historically, it was derogatory and mocking, used to belittle or ridicule someone. Today it remains vulgar and offensive, and its use is generally limited to informal, aggressive, or insulting contexts rather than polite or neutral conversation.
