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.

gooch, it will be like eating a hay bale. Consider shaving that monkey ass of yours and then I will give you the best rusty trombone!
Stewart: Okay, I will do as you say. I may be whipped, but I'm so horny right now.
