The most epic/stupid instrument in marching band. People who play it are either ridiculously skinny or morbidly obese, and have some sort of character disorder. The players are slightly insane, because the instrument weighs about 40 pounds, and it rests directly on a single shoulder for the majority of a 3-5 hour practice.

Good players talk about playing riddiculously loud, and how the susa's suck, and how if they had contra's they'd be much better.
That susaphone player's a real duchebag.
