Definition & Meaning of "shitbucket"in English

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

"Shitbucket" is a slang insult that likely arose in English in the late 20th century, combining "shit" (signifying filth, worthlessness, or contempt) with "bucket" (a container for waste) to create a metaphorical label for someone regarded as worthless, useless, or contemptible. The imagery suggests a person is like a receptacle of unpleasantness or failure. It is used in informal speech, online communities, and casual insults to express strong disdain or ridicule. The term is clearly derogatory and offensive, intended to insult rather than entertain.
