I don't really know anymore. Nowadays when people ask me, I just jokingly say that it's because I'm a kid that says a lot of bull.
My fiance and I learned French together and he began calling me doux (pronounced "doe" in English), which is French for 'mild' and it's normally used with a feminine connotation.
I'm into traditional 'girly' hobbies, so he thought it was fitting. So I began to use it as an online soubriquet.
He also calls me an old lady a lot. Because I love cats and antiques and quilting and cooking and cleaning, as silly as that sounds, and so on.
My favorite pokemon is the sugarfreejazz.
