Entertainment value of the video aside, this thread is extremely interesting from a sociological perspective.
In the not-so-long ago (1985ish and back) in the USA (and Canada as well, I imagine), one didn't have the right to get in someone's face, insult and provoke them, and, so long as the aggressor didn't touch the other person, experience no negative consequences.
In other words, one didn't have the right to be an azzhole without repercussions.
It wasn't in the legal code, but it was part of living in a civil society. Most learned this on the playgrounds, schoolbuses, and vacant lots across the country. Kids learned how to be civil by experiencing, or at least witnessing firsthand, the school of hard knocks.
I graduated from high school in 1986. Fights were a fairly regular occurrence in elementary and middle school, rarer, but still occurred, in high school. Nobody was ever seriously injured, and nobody was expelled, or even severely disciplined for a simple fistfight/ground grapple struggle.
But we learned not to be azzholes to others, or someone would come along and teach us some manners.
That hasn't been the case in schools for at least 30-35 years. And we have adult-aged children, like Mx. Skinny Jeans, who get well into their 20's or 30's and have never learned that lesson.
And then, eventually, they do.
Mx. Skinny Jeans is lucky he only received a concussion and some stitches learning his lesson. It could have been bullets and the morgue.
