A trombone that, when subjected to water or water-based liquids and even air moisture for a long enough time, develops an outer layer of iron oxide most commonly known as rust. It makes a trombone aesthetically and ergonomically unpleasing, as well as difficult to play.
Andy: Hey Bobby, do you want to play my flute?

Bobby: No, I want to play my trombone but it's not working. I dropped it in the water and accidentally left it there for six weeks. Now it is a rusty trombone.

Andy: Well shucks.

From Wikipedia:

Rusty trombone is a sexual act in which a man stands with his knees and back slightly bent, with feet at least shoulder width apart to expose his anus. The other partner typically kneels behind the man and performs anilingus while reaching up beneath the testicles or around the body to manually administer rapid up and down motions of the penis, mimicking the motions of a trombone player. The act is defined primarily by the physical orientation of the partners and the combination of analingus with manual sexual stimulation; however, other positions and variations are possible.
