Question

How do footbal crowds know what to sing at the same time?

Answer 1

they have some secret underground meetings where they discuss things like this.

Answer 2

LOL !!!!    Take me out to the old Ball Game.......

Answer 3

Because one person starts yelling it really loud, and other people nearby join in.. It's a wave effect. And most likely, people who frequent a football game know what the term is, and will yell it to their best.

Also, cheerleaders sometimes start it. It really gets the players pumped - I would know.

Answer 4

It is the frequency of the energy.
