watermelon
n.— «The keynote speaker, William H. Holms, presented a talk entitled, “Wimps, Weirdos and Watermelons,” in which he stated environmentalists were just a bunch of unemployed welfare-leeching Communists. He suggested that the timber industry should join forces with the farming and mining (oil) industries and mount a “hate campaign” against the environmental community, which he portrayed as “green on the outside and red on the inside.”» —“Letters to the Editor: “Hate Campaign”” by Harry Vaughn San Francisco Chronicle Mar. 25, 1991.
