Trombolaphone 

The very large penis that at first scares you but allows a barotone tone when blown

I at first was shocked by the size of the trombolaphone but was able to play jazz with ease

A trombonaphone is what you search up when you try desperately to find the one word that isn't included in the Urban Dictionary.
It has no meaning whatsoever, and it's possible uses are only limited to your imagination.

"Oh my days, Michael is such a trombonaphone."

"Dude, watch me find a word that isn't in the Urb-Dic. Trombonaphone"
