Definition & Meaning of "shitball"in English

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

"Shitball" is a slang insult that likely appeared in English in the late 20th century, combining "shit" (signifying filth, worthlessness, or contempt) with "ball" (a small, compact object) to create a vivid metaphor for someone regarded as worthless or despicable. The imagery suggests a small, unpleasant, and contemptible entity. It is used in informal speech, online posts, and casual exchanges to harshly criticize or mock someone's character or behavior. The term is clearly derogatory and offensive, intended to insult rather than amuse.
