When I found paintings of Recife, Brazil, where my father went on leave from Ascension in 1942, in the April 30, 1945 "Life's War Artists" edition of Life Magazine, I also learned a bit of historic Brazilian World War II slang.
Brazil was neutral until 1942. Up to that point, Brazil's president, Getulio Vargas, said "snakes would smoke" before Brazil got into the war.
