I prefer
organic writer
because the idea of being associated with people who pull other people's pants down is a little bit cringey to me.
Also, I'm a strong advocate for doing what works for you, when it works best for you, however that works for you.
Personally, I tend to sit down and write until I have enough material that I can organize in a better way. I use that rough material to "plot." It would be most accurate to call myself a character driven writer, because my character's conflicts, motives, and personality often dictate what happens at any given moment. Essentially, I am at the behest of the numerous imaginary bullies who reside in my head rent free.
