Trivial, unimportant, petty. The term, sometimes capitalized (Mickey Mouse), alludes to the cartoon character appearing in Walt Disney films which by the mid-1930s had become childish and silly. It acquired widespread use during World War II, when soldiers used it to describe absurd regulations and petty discipline, and thereafter was applied to almost anything. Studs Terkel used it in American Dreams (1979), “We got a Mickey Mouse educational system that doesn’t teach us . . . how the government works.”
