The appeal of the sorority rush videos is likely the escapism that they provide. The videos dig into a fairly niche culture (sororities in the South), and offer a look at what makes them tick.
"You can follow an account and basically watch your own reality show of someone's vlog or something, and for this, because I do think Southern sororities are so niche and so particular to a specific area in America, everyone finds it fascinating," Jenn Ficarra told NBC during a 2021 interview.
NBC also spoke with a variety of other people, including some who may not find sorority TikToks compelling. Obviously, something about the videos has resonated with a broader audience, and many are finding that they have trouble looking away. They get invested and watch video after video featuring their favorite PNMs.
