When an instrumentalist’s (generally those who play brass instruments) penis grows so large and erect, it gives the illusion of a trombone.
James used his massive tromboner to mine the hard to reach places in Suzan’s gaping hole. Amongst the moaning, you could hear a soft, but noticeable “BUM BUM BUM!” signifying the presence of a tromboner.

an act of sexuality when your partner presents the opening of a trombone/trumpet/saxaphone to your genitals and plays wildly.

ex. 3) Julie gave me a tromboner yesterday. it was meant to be.
