I was called Skinny Lizzie as a child at school, because I was skeletally thin. I also got called The Galloping Hairpin when I began horseriding. I always laughed at these names, I was genuinely amused by them and not in the least upset. I think this cheerful response stopped any unpleasant teasing. But as an adult, I do feel overfamiliarity is a domination game, a way of putting someone down. If you suspect this, have a quiet word with the perpetrator and firmly insist on being addressed correctly. If they persist, you can refuse to respond to them. You have to make a stand or they will continue to dominate you.
