“killer” was first previewed on FKA twigs' TikTok on June 4th, 2022, where she’s seen kissing Elite actor Arón Piper for the music video released on July 20th, 2022.

The song follows twigs making her way through the love world and reflecting upon her previous relationships, ones of infatuation where she would lie to herself to make it work.

2013’s “Papi Pacify” similarly explores toxic relationships, and the recurring theme of denial in love is one seen throughout her 2019 album, MAGDALENE.
