slop

Slop is a term with multiple related meanings in English, generally referring to a loose, liquid, or semi-liquid mass, or to leftovers and waste associated with food preparation. The primary noun sense is a mixture of food scraps, water, and other liquids that is often produced in kitchens and meat-processing facilities. In agriculture, such mixtures are commonly called slops or swill when used as feed for pigs. Because of disease concerns, many jurisdictions regulate or ban swill feeding, and safe disposal or treatment is required where it is not prohibited.

A second noun sense describes a thin, watery or sloppy mass of material, such as mud or runoff. It can also denote liquid that has spilled or sloshed from a container, for example, "the coffee slopped over the rim." The verb form slop means to spill, slosh, or splash liquid, or to feed animals with a sloppy mixture.

Historically, in maritime contexts, slop or slops referred to inexpensive, ready-made clothing sold to sailors, or to the associated supply stocks kept in a slop chest. This usage is largely historical but appears in period sources.
