Definition & Meaning of "pissant"in English

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

Pissant is a slang term that appeared in mid-20th-century English to describe a person considered insignificant, petty, or worthless. The term comes from the word for a small, weak-smelling ant, used metaphorically to suggest someone of little importance or impact. Historically, it was derogatory, meant to belittle or ridicule someone. Today it remains informal and insulting, generally used in casual, critical, or mocking contexts rather than polite or formal conversation.
