Definition & Meaning of "douche nozzle"in English

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

"Douche nozzle" is a slang term that appeared in late 20th- to early 21st-century English, building on "douche," meaning a contemptible or obnoxious person, and adding "nozzle" to amplify the insult with a crude, mechanical metaphor. It is used to describe someone who is irritating, obnoxious, or socially contemptible, often in informal speech, online commentary, or comedic contexts. The term is highly derogatory and intended to insult or provoke, and it is never neutral or polite.
