"Meh" fashionable? Old Jewish men in New York City have been reacting with that to everything for as long as I can remember. They alternately use "feh" and the slightly more decisive "bleh" too. For a time, it seemed to be a refreshing expression of shrugging indifference to the world, at least compared to the ferocity of opinion usually found in my Irish ghetto. Then I grew bored of it too. Bleh.
