Garbage men

Two guys, garbage men, grew tired of the language that they had been taught, and invented a new language. This in itself is unremarkable, and happens frequently. But this language, modeled on the trash compactor, was a compact language, fitting neatly into the spaces of words and letters in the old language. It was a model of efficiency, although it had to be spoken and written along with the old language, being dependent on the spacings. That was it's only flaw, really, if you believe doubling is a flaw. They couldn't think of a catchy name, and it never caught on.
