Scrappy to me is defined as using any fabric left over from previous projects. Nothing PURCHASED for the project. Though I know many people actually purchase and co-ordinate fabric for scrap quilts. But, to me that defeats the purpose of what a scrap quilt is about.
Here's one of mine and it's a true scrap quilt.

By the way...someone entered a scrap quilt at our show and was marked down by a judge because the scraps weren't co-ordinated well.... Grrrrr. Scraps are scraps:
