Poet and novelist Jack Kerouac coined the term "Beat" in the late 1940s, but was not until the 1950s that it would become a slang term symbolizing a literary movement by writers such as Kerouac, Allen Ginsberg and William Burroughs. The "Beat" movement rejected the social constraints of the 1950s and reflected a growing disillusionment with the "establishment" and traditional American values. Representative works include Kerouac's novel On the Road, Burroughs' novel Naked Lunch, and poems by Ginsburg such as "Howl".
