The album borrows its title from Jong's controversial 1974 novel, Fear of Flying
, which followed the sexual awakening of a married female writer. It also introduced the phrase "zipless f--k" as a euphemism for a no-strings-attached sexual encounter – a definition both Vanessa and Jong view as simplistic. Vanessa explained in a Songfacts interview
: "While on its surface it represents an unfettered surrendering to all sexual impulses, I've always interpreted it in a broad, more existential way, reflecting a big embrace of all possibility. To get 'zipless' is a philosophical act, couched as a sexual one."
