The titular "Clementine" does not appear in the lyrics, but it is believed to be a reference to Kate Winslet's character in the 2004 movie Eternal Sunshine of the Spotless Mind
. In the film, Clementine Kruczynsk is an unrestrained free spirit whose reckless behavior exhibits traits of borderline personality disorder.
Halsey revealed to Rolling Stone
that Winslet's character was a major influence on her in her pre-teen years: "It was really exciting for me to see a woman on film who was proud and liberated in her own weirdness and in her own non-polite, non-political, non-conformative, inconvenient self."
