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.

Jim: Uh, no it's not! I should know! After all, I've never been to England before but I have cable.
