Used to simultaneously refer to both the flute and trumpet sections of a band. Those within the flumpet section tend to think they're the best, even if they are not. They are brainwashed into thinking that "FLUMPETS R PWN" when, in fact, the Tubonerphone section is the best. 'Nuff said.
Trumpet player: "The flumpet section is obviously the best."
Trombone player: "And by obviously, you mean most definitely not. Sorry to break it to you, but Tubonerphones are the best."
