Drawing is a type of stamping in which a "blank"--a plain sheet of metal--is pressed into a mold by a die, or "plug," shaped like the negative space of the mold. As an example, a disc of metal could be drawn into the shape of a cup, or a rectangle could be drawn into the shape of a sink. It is not always done in one stamp; more complex shapes require progressive stamping.
Drawing is one of the more common stamping operations and can be used to make cups, cans, pots, pans, bowls, artillery shells, car body parts, sink basins, and more. There's probably quite a few things in your kitchen, including the proverbial kitchen sink, that were manufactured by drawing; at one point, your Williams-Sonoma stockpot was just a flat disc of metal.
