In Reply to: "You don't know diddy" Posted by Dan Halyard on October 12, 2006
: My father used the phrase "You don't know diddy" when I thought I knew more than he did. Last week in a meeting someone else used that same phrase "You don't know diddy". Does anyone know the origin and the meaning of the word "diddy"?
You don't know diddly (or diddly squat) is fairly common but I haven't heard it as just "diddy". Here's a link to a previous post that has info on diddly-squat http://www.phrases.org.uk/bulletin_board/1/messages/2517.html
