I think the woman was saying “it fits” in response to what she had just called Rush, which, I too, could not understand. It must not have been very nice. I don’t like most of the people on The Five, but I was always taught not to make fun of people. We then become like the left.
No! She didn't call Rush anything. She was agreeing with Rush that the nickname he gave her daughter fits. He even had her repeat it because he couldn't believe she would agree with him.
