Big, soft, squishy, delicate, and important spherical-ish organs that hang a couple inches below a male's penis. They are kept in a nut sack to regulate the cooler temperature that they need to create sperm. If you hit them on a guy, it is very painful. Guys usually like it when girls feel them and rub them and suck on them.
