Definition & Meaning of "shitdick"in English

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

"Shitdick" is a slang insult that likely appeared in English in the late 20th century, combining "shit" (denoting filth, worthlessness, or contempt) with "dick" (a vulgar term for a person, often implying obnoxiousness or incompetence) to label someone as contemptible, obnoxious, or pathetic. The term emphasizes both moral and personal disdain in a blunt, vulgar way. It is used in informal speech, online posts, and casual or hostile exchanges to strongly insult or ridicule someone. The word is clearly derogatory and offensive, intended to demean rather than entertain.
