A phrase commonly (and incorrectly) said in the place of the British exclamation "pish tosh". It is used frequently by Americans who wish to sound fancy and cultured by peppering their speech with random British words. Of course, by saying this, they are only making themselves seem less intelligent.

A very beautiful woman that is born to a family of French origin. This individual is incredibly good looking and is usually the talk of the town. Many women are jealous of her and want to be just like her, but unfortunately for them, there is no chance in hell of that happening. Any woman who reads this remember that you can never reach the title of "Pish-Posh" like the woman being described. She knows who she is.
"Did you see that beautiful woman from ZP with the initials D.C?"
Yeah man I totally did! She looked Pish-Posh
