When a man or woman of age utilizes their instrument of choice a little more than necessary, it is referred to as "musical instrument intercourse". It can happen with every instrument, but it is most commonly practiced with any instrument that has removable parts (i.e. brass instruments).
Person 1: Have you ever tried musical instrument intercourse?
Person 2: Eww, no. What is it like? I'm by human nature fascinated. Please divulge.
Person 1: Well, I had intercourse with my trombone last night. Everyone gets the urge to do it. And it worked.
Person 2: What was it like?
Person 1: Brassy and vibrato.
