Take about an intense soccer match with intense and passionate fans. Oh, and this is a youth soccer game to boot. What's a typical youth soccer game like in Poland? Well, there are flags and songs and fans stand the entire match chanting. "Bobby's mother brought the oranges. Timmy's mom brought the flares."
No wonder kids in the United States are a bit shocked when they start to play soccer on a bigger stage, whereas European and South American kids grow up playing soccer in an intense enviornment. Well, maybe not this intense, but you get the idea.
