Definition & Meaning of "puke baby"in English

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

"Puke baby" is an informal slang term that likely emerged in English in the late 20th century, combining "puke" (vomit, symbolizing disgust or revulsion) with "baby" (emphasizing immaturity or helplessness) to describe a person who is immature, disgusting, or prone to gross behavior. The term relies on vivid, graphic imagery to mock both childishness and repulsiveness. It is used in informal speech, online communities, and teasing or hostile contexts to express strong disdain. The term is derogatory, offensive in tone, and intended to insult rather than amuse lightly.
