An instrument commonly used for marching bands and drum corps. Basically a trumpet that has suffered both repeated instances of anal rape and consensual anal sex, resulting in a key of F, standing for Fucked in the ass. Often referred to comically as the prison trumpet by those who play trumpet, an instrument that has been spared vicious anal sex.
I'm a mellophone player, therefore I play an instrument that has been raped by me and dozens of other men at the same time resulting in an enlarged bell.
