A person with a nine inch penis. JD9's always wants to have sex and brag about his penis size. Loves to drink and have a good time. JD9's dont care about race, size, or looks.....their goal is to satisfy as many females as possible. They are a very good wingman.
That JD9 pulled out his penis and made those bitches melt.
