TikTok trends are certainly nothing new. If people aren’t trying to figure out how to do the "Wipe it Down" challenge or wondering which ASMR videos are the best, there are new trends to follow and obsess over all of the time. The "barb" trend seems to have had a long shelf life, however, which is likely thanks to being linked to Nicki.
It's still not clear exactly why Nicki fans have been so steadfast in supporting Bernie on behalf of the singer. If anything, it might make more sense for Cardi B fans to be on that train, especially given her public support for him. But here we are, and if TikTok should be used for anything useful, it should probably be conversations about politics.
