So a flubinet is like a flutinet or floboe, but its flute, oboe, AND clarinet combined all together. My band director and the flubinet players made this up after he got tired of referring to the flute, oboe, and clarinet all together (because of songs that called all of the flubinets to play the same thing, or because the flubinet players were all being
obnoxious). It
literally became one of our most used words in band, kinda
hilarious lmaoo.
