The original phrase is "वटीतून ताटात", pronounced as "vaatitun tatat", but with two different sounds for the "t". A "vaati" or "katori" is a small bowl, several of which are placed inside the plate in a meal. The idea is that you are the bowl and your family is the plate; irrespective of whether food is served in the bowl or the plate, finally you are the one who enjoys it.
