We in the United States have another sport called "football," and what the rest of the world calls "football" we call "soccer." I have no idea why, but it's too ingrained in our society to change that. Basically, our football has a spheroid-shaped ball that we throw and kick. Each team has a turn to try and score, and the defensive team can try to steal the ball.
It makes a lot of money, and it makes people act crazy. I love it!
