These frat boys aren’t shy about their love for Taylor Swift’s latest single, “Shake It Off.”

In a now-viral YouTube video, the Delta Sigma Phi brothers at Transylvania University in Lexington, Kentucky, lip-dubbed their way through the catchy tune, giving us all an entertaining look at fraternity life.

It isn’t all fun and games at the Delta Sigma Phi house, though. At the end of the video, the fraternity brothers linked to a fundraising campaign for the Leukemia & Lymphoma Society’s Light The Night Walk fund, in honour of an alumni battling lymphoma.

More than 3 million people have viewed the video, Taylor Swift included. The country-turned-pop star was so impressed by their efforts that she invited the students (and their dates) to one of her upcoming concerts.

The guys were thrilled.

"We were all in the hall together and somebody ran in the room and was like, Taylor Swift just Tweeted at us. We checked it, and [there were] a bunch of people just screaming and yelling and running up and down everywhere," 21-year-old Daniel Lyvers, president of the fraternity, told People.

"It was super exciting, because we didn’t expect it. All we were really hoping for, after it started to get popular, was a retweet. And I got two and another guy in the chapter got two. And then she invited us to her concert, and I just responded with, ‘We accept.’”

Lyvers told People that the fraternity hopes to take special dates to Swift’s concert.

"We talked [about] maybe working with the Big Brothers Big Sisters program in Lexington and seeing [if] maybe they can be our dates to the concert, or if there was anything that Taylor Swift’s team had in mind of something that we could do."

We’re pretty sure there are no haters to shake off here.
