What is Cool to do or not Cool to do in the Wrigley Field Bleachers

It's "cool" to be in the bleachers at Wrigley Field, but is what you are doing "cool"?

I took my youngest son to the Cubs game Sunday, it was his first experience of being a "Bleacher Bum" at Wrigley Field. The atmosphere in the bleachers is amazing. Everyone is there to watch the Cubs, and just enjoy themselves.

There are plenty of bleacher activities as the game is being played, finding out which bleacher side "sucks", failed attempts at the wave, and maybe just maybe some gambling.

But what is considered "cool" and "not cool" to do in the bleachers? Sunday was a very warm afternoon, and the concessions in the bleacher section are pretty incredible so I decided to try something I've never had before. With that, I grabbed this blue frozen drink in the collectable half yard. This purchase was met by a pretty harsh reaction by a good friend. Comments ranged from, "are you kidding me you big girly man" to, "if I was with you, no way I'd let you drink that".  For the record, it was delicious and packed quite a punch.

Are there rules you must always follow in the bleachers? Can a grown man enjoy a frozen blue drink?
