This first became a thing when a fan shouted this during Swift's performance of 'Delicate' during her Reputation Stadium Tour.
When Swift sings the line: "We can’t make, any promises now can we babe, but you can make me a drink…,” there is a brief pause before the verse where fans chant: "1, 2, 3, let's go b****!"
Clearly, the 'Anti-Hero' singer has heard this chant loud and clear during her Eras Tour shows to include this fan lore in her latest post.
It's not the first time Swift has released a film documenting her career milestones, as on Netflix there is theMiss Americana(2020) documentary that chronicles her musical journey and details her personal life.
While fans of the 2017 reputation album can relive the live shows as the stadium tour was recorded - and both films are currently available to stream on Netflix.
In 2020, the Folklore: The Long Pond Studio Sessions where Swift performed the songs and gave insight into how they were made was released by Disney+.
Most recently, Swift released All Too Well: The Short Filmin 2021 where fans can watch the short film on YouTube and at the time it was also released in select theaters by Universal Pictures.
