Pumpkin Liquor?

I have heard of something called Pumpking Liquor, and was wondering if anyone had a recipe for it? I dont think it is real complicated, like take a good sized pumpking open the top take out all of the seeds but leave the meat in, and pack it with brown sugar, then put it in some place dark and every few days roll it around a little.....so far thats what I have heard from people but I cannot find a recipe for it....

I have heard Harvest Grand Pumpkin Spice Cream Liqueur is the only ingredient you need.
