we play select ball in the fall (my son is 11 and plays on an 11AAA team, and a 12U AA team), and Little League in the spring to keep a balance. Our Little League is such a huge part of our neighborhood you pretty much have to play because all the kids from the tournament team play Little League. Our Little League is one of, if not the largest in the country despite a relatively small neighborhood.
I've seen all of what you described above. It's unreal. you always know when "baseball" guy is there. He has the requisite 55 pounds of beer gut, 100% has a goatee and some form of Oakley style shades to go along with his surly attitude and no fewer than 3 tattoos. They're usually pretty friendly after the game if they have won. If you get to where you can beat them, and our team beats those kinds of teams regularly, they absolutely disparage, belittle, and chastise everyone around them. Out at BBUSA in Houston what I have just described is the RULE and not the exception. It's even worse down south at Big League Dreams where you combine an even more league City redneck version of "baseball guy" with a full bar. We won't even play down there anymore.
I once saw a dude give a kid (happened to be his son) a steal sign. Kid takes off to 2nd, batter hits a smashed line drive to the 1B who catches it basically standing on the bag to double the kid off. Keep in mind they're up on us by 6-8 runs. This is a team my son plays on so he can play up in age, not his normal team. anyway, dude absolutely goes batshit, ballistic bonkers on the kid to the point where after berating him all the way back to the dug and into the dug out, he took the kids bag out of the dug out, threw the kid against the fence, and made him sit outside and think about his mistake. What the mistake was, I have no idea. It's called baseball, and the coach is the dumbass that had a hit and run on, up big IN A SEED GAME. Here he is. For those who are not aware this is the ultimate "baseball guy".
