marslops
n.— «Leased by Trafigura, a global oil and metals trading company, it was pausing on its way to Estonia to unload what the company said was 250 tons of “marslops” or “regular slops.” That is the wash water from cleaning a ship’s holds, which would normally be laced with oil, gasoline, caustic soda or other chemicals.» —“Global Sludge Ends in Tragedy for Ivory Coast” by Lydia Polgreen, Marlise Simons in Abidjan, Ivory Coast New York Times Oct. 2, 2006.
