Another word for a "handjob". It is normally used by tools trying to describe to his tool friends what sexual pleasures he recieved. This is generally used by middle school "bros" who are too immature to know what oral sex is.
Andrew:"Hey man my 13 year old girlfriend gave me the handy dandy last night."
