deriv. (Old West--when a person who 'shot from the hip' pulled their trigger in a proper draw (ie from a hip holster.) This is in direct contrast to a person who arrived to the gunfight with guns drawn. By extension, a person who 'shoots from the hip' possesses the positive quality of handling a situation in the prescribed mode.)
