I don't think this is truly anything new. It seems more to be a feature of teams who get along really well.
We all develop little rituals. Some invisible to others, some right out there. Sign of the cross, fist pump, head down for a second, whatever it is. Everyone has something. Some have many somethings.
But collective rituals seem to develop most easily among groups who get along uncommonly well. Who are tight. Like the 2022 BaseVols. They are tight, and have developed a whole family of rituals, involving hats and fur coats and falling to one's knees, and hands over the eyes, and all kinds of stuff. That's them.
I wouldn't say that's new in the 2020s. I've been on teams and in units that developed rituals, from all the way back to the 1970s.
It's just really evident with these lads. Because they're a team in the purest sense of the word. More than most.
Go Vols!
One thing I learned from playing a decade of softball:
If everyone on the team has a nickname, they are harder to beat than a team yelling "Get a hit Andrew. Way to go Steve. Nice catch Joe. Good slide Stan"
