boner
(n.) a crush on a trombone player. The most intense kind of boner is had by a trombone player, for another trombone player, creating perhaps the nerdiest of infatuations and resulting in spontaneous combustion.
Becky: OMG I have the BIGGEST crush on this trombone player I played with in honors band.

Mary Claire: Becky... I'm afraid you have one of the most extreme boners I have ever witnessed in my entire life.
