Kim Kardashian Caught On Tape Punching Kourtney in Heated Argument


One of the most infamous moments in KUWTK history is when Kim hit Khloe with her purse and said "dOnT bE fUcKiNg RuDe!"

Now there's a sequel to that cringe-worthy catfight with "DoNt EvEr CoMe aT mE LiKe ThAt" -- where Kim is shown straight up punching Kourtney in a heated argument in Season 18.

The clip begins with Kourtney shouting at Kim, throwing a water bottle and then lunging at her, so it's not like Kim was the only one getting physical -- but it's still pretty disturbing to see actual punches thrown.

What the hell is going on here?
