The phrase "Roaring Twenties" was derived from the "Roaring Forties," the very powerful westerly winds that blow between 40 and 50 degrees latitude in the southern hemisphere. The Roaring Forties could hugely speed sailing ships - but also swamp and sink them. 2/x https://t.co/nuX1YJTvJb — PolitiTweet.org
