Flat out means as hard as possible, as fast as possible, with the maximum effort possible. The term flat out is also used in North America to mean utterly, without equivocation, out-and-out, absolute. When used as an adjective before a noun, the term is hyphenated as in flat-out. The term flat out is known at least from the 1930s to describe going as fast and as hard as possible, probably derived from the act of depressing an automobile accelerator to the floor. In the 1830s in North America, flat out meant to fail utterly. How flat out came to mean absolutely and without equivocation in North America is unknown.
