A variation on the rusty trombone, the rusty French horn consists of a man giving a rim job to a woman, while also fisting her. This is reminiscent of a musician playing the French horn, as he places his hand in the bell of the horn to alter the pitch of the sound.

It's a take-off of the rusty trombone, where you 'toss the salad', but instead of the handjob, you insert your fingers like you're playing a french horn.

(ex. female version of the rusty trombone)
Bill gave me a rusty french horn, but I had some dingleberries that obstructed the air passage, so his tone was heavily affected.
