O.J. Simpson's reputation as a violent convicted criminal is already SO HORRIBLE, it's basically impossible to inflict even more damage to it ... so says the Vegas hotel locking horns with Juice in a defamation case.
As we previously reported, Simpson's suing the Cosmopolitan of Las Vegas over a Nov. 8, 2017 incident in which he was kicked off the property following an alleged drunken incident at a hotel bar.
In the wake of the incident, hotel staff told TMZ ... Simpson was wasted and became disruptive, getting angry with employees ... and glasses broke at the bar.
