"If he drops my name, then I owe him nothin' / And if he spends my change, then he had it comin'." It seems like Swift is referencing Harris's infamous Twitter rant about the singer following their split. While the couple's breakup seemed amicable initially, things took a turn for the worse when Swift's camp confirmed that she wrote Harris's hit song "This Is What You Came For" under the pseudonym Nils Sjoberg in 2016. The statement caused Harris to post a series of heated tweets, which made reference to Swift's then-boyfriend Tom Hiddleston and her feud with Katy Perry.
