The palm of your hand. As in, the place to write down the main points you want to hit in a speech or an interview, if you're too dumb to remember them.
Pioneered by former
Alaska Governor Sarah Palin during her
creampuff interview at the Tea Party Convention in Nashville on
February 6, 2010.
I knew the interviewer would ask me what my core
principles were, but I couldn't remember them because I'm a
complete moron, so I wrote them on my Palin Teleprompter and discretely checked them during
the interview. I'm sure no one noticed!
