Definition & Meaning of "shitbird"in English

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

"Shitbird" is a slang insult that likely emerged in English in the late 20th century, combining "shit" (denoting filth, worthlessness, or moral lowliness) with "bird" (often used metaphorically for a person) to create a vivid label for someone viewed as contemptible, irritating, or morally low. The term draws on the idea of a small, annoying creature associated with mess or nuisance. It is used in informal speech, online forums, and casual insults to express disdain or frustration toward someone. The word is clearly derogatory and offensive, typically intended to ridicule or demean rather than entertain.
