The History of P Supers

The idiom, a P super, was first used to describe the thick choking smogs that settled over London caused by lots of people burning fossil fuels in a close vicinity as early as 1200. Smog is a portmanteau word, a mix between the word smoke and the word fog. In fact, since the clean air act of 1952, an act of Parliament, a law which was brought in to clean up the air in London ever since then, we haven't really had that kind of smog or fog that we used to have.
