orchestragasm
A long passage (or series of long passages) in a symphonic work where the intensity and climax of the orchestral forces are enough to give the listeners, performers and/or conductor a full-body orgasm.
Listening to a philharmonic work from many avant-garde classical composers, especially in symphonies or operas, can cause an orchestragasm of fully-erect ejaculations. A great example of this is Henry Brant's 'Kingdom Come" for two orchestras and organ.
