The song introduces a robbers and thieves metaphor that appears in different guises throughout Reputation
. Taylor explained during her iHeartRadio Reputation Album Release Party
"The way that's presented in '...Ready For It' is basically, finding your partner in crime, and it's like 'Oh my god we're the same, we're the same, oh my god! Let's rob banks together, this is great!' And we'll hear that theme carried on throughout the rest of the record, but not exactly in the same way as you heard it in '...Ready For It.'"
