I think Khabib made that comment to make Conor think he fell for the trap making Conor over confident. Khabib is playing 4D chess man!!
In which case well played Khabib.
I think he was able to get under a lot of opponents skins successfully. That is what he is after. I think like any actor, when he can't play his role convincingly to his opponents, he undermines himself. This was also different because it didn't look like he was having fun out there. There were a lot of hilarious moments in his trash talk to nate for example but here he was just loud and angry and couldn't get through Khabib's wall successfully.
He was onto something with the khadirov thing but if you look at who khabib is, the only thing that I think could truly offend him would be to call him a fake Muslim.
Your missing it, he wanted to come off as an alcoholic, which he sold very well
