"We both mock type as we speak."

I was watching CNN and somebody said this about herself and her sister.

What does this mean?

I can take this two ways - literal or some sort of ____. Once again I'm lost for the proper word.

But I'd just thought I'd ask because I've never heard of this before.

It would be great if someone would enlighten me.

Thanks!!!

I've converted to lurk-ism... hopefully only temporary.
