I've only read page one.....I'm betting New Jersey
We play in NJ and I’ve never heard an opposing teams parents participate in the softball chants lol. We’ve gradually moved our 12u team away from them in favor of just cheering on their teammates.
Don’t get me started on cowbells. Had a parent break them out in response to the opposing team rattling them. When I yelled out no cowbells, I was treated with the obvious response of more cowbells?
In between games last year i was watching a game and made a comment to a woman standing next to me about cowbells. Turns out she was the parent of our next opponent and she broke out not a cowbell but a bullhorn.
