You have definitely been patient!
My SIL calls all her kids names (she thinks to be funny/affectionate) but I find it really horrible. She calls her one kid "Dumbo" because she said he has big ears (he so doesn't but let's give him an issue with them!), she would always tell her other boy that he has ADHD etc etc. I'm not usually around to hear it but I hear about it from my mom/siblings.
