It's quite annoying to hear retarded over and over again, though I laughed when I read the rest (sorry ^^")

For me, of course, it's the retarded thing too.
It was quite often that it became a usual for me to hear it and say it (though I should not -_-")
Other than that.. Thanks God, my mother hates any of us to utter such words and she herself doesn't utter them :) we were raised like that :D
