The phrase "terrible, horrible, no good very bad day" originated in 1972 as part of the title of a book by Judith Viorst, Alexander and the Terrible, Horrible, No Good, Very Bad Day.
The author's theory about why the phrase is being used on a recurring basis now, according to the Newsweek article, is that the children who were raised on the book are now the adults who are, "running the world."
Amazing how certain words and phrases come and go and come again. The evolution of language sure is fascinating.
