Did I hear correctly? "mei cuo"
When I'm listening to an online radio station in Mandarin Chinese, and the host is talking to a guest, I sometimes hear the host say something which sounds a bit like "may tsor" (my english interpretation), which I think is maybe "mei cuo" (pinyin). It seems to be a very common saying, I seem to hear this all the time. It's not part of a larger sentence, instead the guest says something, and then the host quickly responds "mei cuo", and then the guest says something else.
I looked it up in a dictionary and it said "méi cuò" ( 没错) means "That's right" or "Sure!" or "That's good".
Did I hear it correctly ? Is this the correct word, and is it a common saying? Or did the host actually say something different?
