When a woman (or man) is giving a Man a blow job while humming (like a trumpet) and using three fingers to stimulate the balls.

The goal of the rusty trumpet is not for the man to orgasm, but for the man to fart.
Man: Hey baby, you want to give me a rusty trumpet?

Woman: What's that?!?!

Man: Well, you slob on my knob like corn on the cob, then use tree fingers to massage my balls, the job aint done until I fart! Wocka Wocka!
