Smokey Bear (n.) Look up Smokey Bear at Dictionary.com
"state policeman," 1974, from truckers' slang, in reference to the wide-brim style of hat worn by state troopers (the hats so called by 1969). Ultimately the reference is to an illustrated character of that name, dressed in forest ranger gear, introduced in 1944 by the U.S. Forest Service and the Wartime Advertising Council in a campaign to lower the number of forest fires in the West.
