I know American's aren't the only one's but they seem the worst for sure. It's not about excitement, of course people are going to be excited but its about timing and knowing when to shut up and listen to music instead of shouting over it.
dude,
why do you spread hate like that? seriously you can state your opinion, and i will listen, but not if you make blanket statements about other people. obviously not all people of certain culture are to blame for the actions of a few in that culture. and besides, we all know that everyone can be annoying regardless of national orgin.
