My nickname is "TaiDon." It was started when my wife call me like that.
"Tai -" comes from my first name.
"- Don" is used in old stories in Japanese like "- san." But, my "- Don" comes from "donkusai", means stupid in English.
My wife has a funny and bad mouth.
By the way, I'm trouble what should I be called. I don't know a similar nick with my first name. Of course, "TaiDon" is not very good. But it is shameful fore that I use some English streo type nickname as Jack, John and George.
My trouble maybe contolinue for a while.
