My last name is Dishman, so when the boys were playing sports, they always got called "Dish" by their coaches. In school, they were a grade apart so the school coach started calling them "Dish" and "Little Dish." The principal always called them that, too. When my daughter started school, he decided to call her "Little Little Dish." (He's just creative that way!)
One day we all walked in to school together, and he greeted the boys ("Hi Dish, Little Dish.. here's Little Little Dish...") and then he realized I was there too and said "... and here comes Momma Dish." I thought it was cute! So I use it for my email and screen names.
So how did you get your name?
