A flatulently melodic group of people creating music with their orifices. The most impressive pieces of music are created by the corn eye by drinking brews and having eggs for breakfast. Nothing is more potent than beer farts combined with the forces of egg farts. Use of a clothespin or gas mask may be necessary when enduring a live performance of an orificetra.
All us back in Geek Squad had mad swamp ass from that air conditioner being broken and gas from drinkin beer the night before, we were all tooting from our fart boxes creating music as an Orificetra. We played the brown note sonata which was finished by a solo from the Schocker in high notes from his well tuned corn flute.
