I'm wondering what the real meaning of the word "Duh" really stands for. I've always though of it as an ironic word, expression for "Duuuuh, didn't you know that, that was so obvious... ").
I've used "Duh" in a couple of posts but I've been called cruel both times for doing so.
Can someone explain what that word really means, stands for?
Is it really an... evil word?

This post doesn't make sense... does it?
