Definition & Meaning of "shitpicker"in English

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

"Shitpicker" is a slang term that likely emerged in English in the late 20th century, drawing from the literal act of picking through feces to create a metaphor for someone considered disgusting or obsessively focused on filth, degradation, or trivial nastiness. The term combines "shit" (signifying filth or worthlessness) with "picker" (someone who selects or meddles), giving a vivid, contemptuous image. It is used in informal speech, online discussions, or storytelling to harshly criticize or mock someone's behavior, habits, or moral character. The word is clearly derogatory and insulting, rarely neutral, and conveys strong disgust or disapproval.
