The act of tucking your penis and nuts between your legs and holding your legs together tightly to look like an ugly vagina (just like your sister Sally). Otherwise known as the Buffalo Bill. This maneuver is usually followed up by spinning around and bending over to produce the fruit basket.
My bitch girlfriend left me on the side of the road in Gaysville, so I had to sister Sally to get a ride. It's ok though because I got to show my fruit basket when I got in the truck.
