The phrase "table scrap" refers to small pieces or remnants of food that are left over from a meal, typically after everyone has finished eating and cleaned their plates. These leftover bits may be considered not worth serving or eating on their own, so they are often thrown away or given to animals as sustenance. In a broader sense, the phrase can also refer to any small or insignificant remnants of something, such as scraps of paper or leftover materials from a project.
