IDGAF is a track from Dua Lipa's self-titled debut album, released in 2017 and issued as a single in 2018. Short for I don't give a fuck, the song was written as a blunt kiss-off to an ex who tries to return after moving on. Its direct chorus made it easy to excerpt online, and short clips of the hook spread on TikTok and in fan edits as a shorthand for being unbothered. The phrase now works on its own, even for listeners who never play the full song.
