Bling is the ubiquitous word/phrase of the moment - I heard it on morning radio yesterday, a sure sign. It seemed new and fresh a month ago and now I'm tripping over it everywhere - presumeably it's capturing something of the imagination of the moment. And in another month or so it will have gone. It has something both hopeful and cynical about it all at once.
Previous words/phrases of the moment have been segue, "in the same ballpark", "singing off the same page" and "it's not rocket science"
Does anybody else have any other words or phrases that have soared briefly then fallen from grace?
