Stands for "Dick fart". It's when a girl farts on a guy's dick and the guy gets turned on from feeling the vibration of the fart and the great smelling of it. Pretty much its like putting a vibrator on your dick while you are smelling a great breakfast, lunch, dinner.
Today at the school dance, I was freaking with Angelica and she farted on my dick and it felt good and smelt like pizza. She just gave me a DF.
