What's a Mommasissy?

I was just perusing my favorite blogs and came across a post from Erika about her nieces who call her "Mommasissy." I've never heard the term before. Maybe it's a SUTHUN THANG. And what does this have to do with Pizza by the Sea? Well, according to her blog, her precious nieces Morgan & Paige were in town this weekend and specifically asked to eat at our place. I have decided the letters on their dresses indicate that they would like More Pizza, so hopefully these cute little pepperoni monsters will come by again soon. Check out their uber-talented aunt's work here.
