Kelvin isn't built for shit talk or this stupid act he is putting on.we all know that Conor is married/kids, but his public image is that of a 'playboy'.
so Kelvin loses this exchange badly.
He doesn't come across as bad as some do ( looking at you Marty ) but it just doesn't fit.
Mc Gregor is celebrated by the "fans" for being a dick head.
Kelvin loses by engaging at all in the first place, or for listening to which ever clown convinced him walking around with Cejudo's belt was a good idea.
