According to an article in the March 9th Newsweek, the phrase "terrible, horrible, no good very bad day" has made appearances in 50 news stories about certain politicians since the spring of 2007. The article also mentions that references to the phrase, "all but disappear," a few years prior to that.
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.
