Well they do..but I think it has something to do with those sticks they slap together. Many nations differ on how they cheer thier team on..Europe they whistle when they disagree with a call...Where as in Philly they throw rocks, bottles, appliances and what have you when they do. Some folks in the Midwestern US like to use those cowbells at football games. Just like in South Africa they used those plastic horns...whatever they were called.
