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.

When a female or male(in homosexual scenarios) grabs their partner's penis from behind and plants their tongue and lips on their asshole. Then he or she proceeds by licking and possibly eating out their partner's asshole. At the same time, he or she gives them a handjob. This movement that is performed is very much similar to playing a trombone.

Stewart: Okay, I will do as you say. I may be whipped, but I'm so horny right now.
