A grease cock is when you never wash your dick and balls, so that your junk builds up a heavy layer of grease. With your penis being so greasy, you won't need to worry about using lube, or having a girls vagina dry up on you because your dong is always slick.
My boyfriend goes full on grease cock! We never have to use lube during anal!
