Ultra's Home Advantage in Football

Home advantage in football is a huge advantage for the home team. Ultra's make tons of noise they psych up the home team and can drown out the opposing team's ability to even call plays but it ain't nothing like this. The biggest humiliation a given ultra group can have is to have that flag stolen from them by an opposing ultra's upside down so there's very ritualistic capture the flag style everywhere. It started with latin american torsidas then spread to Argentina and Brazil during the world cup and was brought to nfl fans too.
