1. (n.) A multi-purpose response, primarily used to imply a degree of indifference. Tone of voice and circumstance often implies a meaning. Can be used when you don't want to answer an awkward or embarrassing question, or if you just plain have nothing else to say, and you want the other person to interpret the "meh" however he/she chooses. As in: Q: "What do you think of my new dress?" A: "Meh." or Q: "What do you want to do tonight?" A: "Meh."
