Earlier today, the official KUWTK YouTube channel uploaded a new promo for season 18, in which the two can be seen getting into a pretty serious physical altercation after Kourtney throws a bottle at Kim and says, "I will fuck you up, you literal cunt."
And though Khloé can be seen trying to break up the fight, Kourtney and Kim continue to scuffle, which eventually leads to Kourtney slapping Kim's face. Later in the teaser, Kim can also be seen yelling, "Just get the fuck out of here. I don't even wanna see your fucking face," to which Kourtney retorts, "I don't want to be near your fat ass!"
Needless to say, it didn't take long for the internet to start meme-ing the clip, with many users commenting on the dramatic nature of the fight.
"Damn, Kourtney slapped tf outta Kim," as one user said, while another referenced Kourtney's new lifestyle endeavor by writing, "so Kourtney gave Kim a gluten-free ass whoopin."
Meanwhile, others egged on Kourtney with commentary like, "... everyone happy Kourtney finally slapped tf outta Kim k. I mean it's been a long time coming y'all forget she is Kim's big sister!!! Yes sis!"
To add insult to injury though, others joked that Kourtney was "#TeamTaylor," as a nod toward the rekindled feud between Kim and Taylor Swift that was recently spurred by newly leaked footage of Swift's infamous call with Kanye West.
"Kourtney Kardashian leaked the footage and is a Swiftie, I won't hear otherwise," as one person wrote.
