I'm sorry, but I don't even find that amusing. I've gone to concerts with girls like you near my seat and wanted to knock them off their ass. People are there to hear the band and for those who scream the way you describe...it truly ruins the show. You might as well piss on everyone around you. You people don't even truly pay attention because you are just screaming just for the sake of it because your favorite band is on the stage. It doesn't occur to you to actually listen or the fact that you are making everyone around you miserable. They didn't pay 50 to 100 dollars to hear you interupt their favorite band throughout the show.

So lets say I'm seeing Bon Jovi and they are doing Something To Believe In and I have one of those idiot girls near me.....then the experience is like this:
"I lost all 'AHHHHHHHHHHH' and his re-'AHHHHHHHHHHHHHHHHH' to someone new."

That is not cute at all and the whole time I'll be hoping you get punched directly in the face to shut you up.

The next time that happens I'll see to it security carts your distruptive ass off or at least shuts you up.

So if you are truly one of those girls, think about that and how the reality is outside of your own little world.

Get excited....but appropriately. That means sing along at appropriate times. Shout out when you are asked to by the band, not while they are in a poignant moment in a song. You might think I'm a dictator or whatever, but your imposition on others is far worse.
