Definition & Meaning of "turd burger"in English

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

"Turd burger" is a slang term for a person viewed as contemptible, obnoxious, or worthless. It appeared in late 20th- or early 21st-century English, combining "turd," a vulgar word for feces, with "burger" to create a metaphor suggesting someone made entirely of something disgusting or worthless. The term is used in informal, mocking, or hostile contexts, often online or among peers. It is vulgar and derogatory, never neutral, and conveys strong disdain.
