Techish

Techish: noun. The language spoken by stage technicians all over the world. Even if two techies do not share the same native language, through the power of techish, they can still communicate enough to be able to successfully run and manage a production. Unfortunately, not enough research has gone into techish, to understand how exactly this can happen, but the phenomenon is well documented, as early as from the first stagings of Mozart's Don Giovanni, where the Austrian and Czech techies somehow managed to cooperate despite not speaking each other's languages whatsoever.
