This guy is like 53 years old, what is he doing at a mumble rap nightclub? Yeah it's definitely not a good look, I don't care what anyone says you should never hit a woman, a guy of Dana's size should be able to take it, unless she's some behemoth who can inflict serious damage like Gabbie Garcia.
He apologized, not much else to it, they were both drunk, she hit him first, shit happens, it's between them. Didn't look like he was going full force but yeah, this is no surprise to me considering Dana's temper. Pretty fucking brazen to slap a women in public though, that can get your ass beat but he does have Dana White privilege as T-Ferg likes to say.
