Definition & Meaning of "pig shite"in English

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

"Pig shite" is a slang insult that appeared in English, particularly in British or Irish usage, in the 20th century, combining "pig" with "shite" (a vulgar term for feces) to describe someone as worthless, contemptible, or incompetent. The metaphor equates a person's character or abilities with something physically repulsive and worthless. It is used in informal, often hostile or mocking contexts, such as conversation, media, or online posts, to express strong disdain. The term is clearly derogatory and intended to insult; it is never neutral.
