Today, out of the blue, Zi stretches out her arms and says, "Hagyoo!"

I responded, "what’s that" so she kept saying it over again.  Finally, she shimmied over to me with arms outstretched and hugged me.  Then she smiled at me and said, "hug you!"

*ooooooooooooh!*

So her newest phrase is "hug you" and she does it all the time now.
