Jeff Suppan is now a pitcher with the Milwaukee Brewers. He was formerly with the St Louis Cardinals. I'm not sure if the Brewers fans do it but the Cards fans used to be heard saying "Soup" when he pitched. If someone didn't know what they were saying, they might have thought they were hearing "boooo" because of the similarity of the sound.
