Definition & Meaning of "toilet baby"in English

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

"Toilet baby" is a crude slang term for a person regarded as disgusting, worthless, or socially repellent. It likely emerged in late 20th-century English as a shocking metaphor, combining "toilet" (associated with filth and waste) with "baby" (something vulnerable or human) to insult someone's very existence. The term is highly derogatory and used mostly in informal or hostile contexts, such as online arguments, trash talk, or dark humor. It is never neutral and is intended to provoke disgust or ridicule.
