Two weeks ago, HarperCollins dictionary added “meh” as an official entry for its 2009 edition. Etymology: Murky. Possibly the Simpsons, a response given by Bart and Lisa when Homer suggests a day trip in a 2001 episode. Definition: refers to an apathetic response. It really has a striking similarity to “eh,” used for the same purpose. I suppose the “m” at the beginning added just that scholarly touch that HarperCollins needed.
