Rob Kardashian posts disturbing video on SnapChat calling Blac Chyna a pshyco b***h, shows off bloody scratches on his arm

Rob Kardashian yesterday posted a disturbing video on SnapChat calling his pregnant fiancee Blac Chyna a pshyco b***h while showing off bloody scratches on his arm.

Rob's face cannot be seen in the video but he clearly says; “Look what she did to me! Crazy a**! Psycho b****!”, before Chyna reaches out to punch him. The video was definitely before he deleted her from his IG page
