From the opening credits, I was immediately struck by Charli XCX's lyrics: "I need that bad boy to do me right on a Friday / And I need that good one to wake me up on a Sunday / That one from work can come over on Monday night / I want 'em all." This song plays over a montage of sweaty men dancing in the club, or what Fennell referred to as "slo-mo crotch thrusts of a thousand nightclubs" to Vanity Fair.
The song is ironic, mostly because it paints a bubblegum facade over a menacing situation, just like Cassie is moonlighting as an unconscious woman to teach would-be rapists a serious lesson. The song is also significant because Cassie quite literally wants all the boys – to pay for what one did to her best friend, Nina.
