Yup, it's "the stuff" left over after I make something. If I have a yard of fabric, and cut half of that into pieces, but then have triangles and doodads and weird rectangles or squares that are not quite squares....scraps. The "whole half" is not scraps, it is "stash".
A scrappy quilt can be either "made from scraps" or pull a bunch of different colors from FQ or yardage to get that sparkle because there's a bunch of different fabrics.
