rat spill
n.— «But worse than an oil spill, in the view of wildlife biologists working furiously to protect millions of exotic animals, the freighter, if it got close enough, could cause an even greater environmental calamity: a rat spill.…Scientists say they now fear rat spills more than oil spills, which can eventually be cleaned up.» —“In Alaskan Islands, Fearing a Spill That Comes on Legs” by Sarah Kershaw in St. Paul, Alaska New York Times Dec. 28, 2004.
