As a noun, adjective, and adverb, this term is spelled the same way: helter-skelter. It means to be disorderly, confused, hurried, or haphazard. Outside of the United States, the noun form can be used as a name for a certain kind of amusement park ride that twists and turns around a tower.
Helter skelter, without a hyphen, is often used for the title of songs, books, or movies.
The exact origin of the term is unknown but it dates from the late sixteenth century.
