Yeah not quite sure about the question but I will take a stab:

You are free-rolling when you have the current nuts and any draws that hit leave you with the nuts.

So, as an example, not long ago this hand happened to me (in limit):
I have AKs, 2 other players have AKo.
Flop comes TJQ with 2 of my suit.
Capped every street. I hit my flush on the river- take down a nice pot.
That is an example of free-rolling.
