There were several stories coming out of him being a dick backstage, he got heat for bringing "unsavory" people backstage to a show (and to be considered unsavory in wrestling imagine what that must mean), to the point it was claimed Roman kicked him out of the locker room. Plus a lot of stories popping up from people not in the business on Twitter where they are saying Enzo from WWE showed up at their club/bar/exotic dancing establishment and acted like an entitled asshole.
