This stunt can be done by either two guys or a male and female. this is how it works. lets take the two guys for example, one will get on his knee's and will be facing the guys ass while he stands ( note: must be naked for stunt to work ) . the one on his knees begins to give the one in front a reach around.( just like using a trombone ) but trombone's are used by not only your hands but your mouth. so this is where the "rusty" part takes affect. the one on his kness will begin licking/eating out the ass infront of him. there you have it folks, the rusty trombone!
- The Rusty Trombone sceene was cut from the movie brokeback mountain because its a high paying manuver.

- " sick dude! i just heard that guy over there talking about giving his boyfriend a rusty trombone ! "

- * Don't do this unless your paid LOTS of money ( more that what Bill Gates has) or your so drunk and the world is going to end the next day and you have nothing else to do *

The act of performing anal cunnilingus while reaching up above the testicles to manually administer quick up and down motions to the penile shaft; resulting in a violent yet pleasant explosion. It is then customary for the female to then give a quick blow into the anus for good luck, the lips blowing into the anus sounds very similar to a trombones sweet melody. This was introduced to the Americas in the late 50's.
While receiving a rusty trombone I lost control of my bowels.
