Our last name is Balzari. I've just discovered that my daughter is going by a shortened version of her last name as a nickname. Her friends now call her "Balls." I discovered this because a friend of hers saw her from across the street while we were walking home yesterday and to get her attention started shouting "Balls! Hey Balls." I find this to be appalling. She doesn't see what the big deal is and thinks its cute or funny.
What's worse is that my wife knows all about this. When I brought it up to her, she told me that our daughter has been using this nickname for some time now and even has social media accounts with the handle Balls(her soccer number).
Am I right to think I need to put my foot down on this?
