The grandy is a highly deviant solo-sexual activity in which the (most commonly male) participant gives himself a handy after soaking his hand in water in order to develop wrinkles and simulate the tactile sensation of an old man or woman's hand.
The grandy can be used in conjunction with other common solo-sex acts committed mainly by men such as the stranger.
"I soaked my hands in my warm soapy tub for an hour in preperation for a kick-ass grandy."
