On an Apple computer the 'Ctrl' button is the '
Apple' button. The command for 'print' is '
Apple P'. When you print something off the computer, you make it real and tangible, just like rotten apples are turned into apple juice. Thus, 'Applejuice' is
slang for printing a page off of the computer. It is also used as slang for creating something or making something happen.
"Applejuice those documents I sent you, okay?"
"I
need to applejuice something for my mom for
Christmas."
"You gotta applejuice something in
your life!"
