Writing sh*t just to get it down on paper…

Does anyone else ever just write their story knowing what their writing is crap so that they can go back and edit it into something resembling quality later?

I feel like I’m doing this right now with my second book. I know where I want my characters to go, but I can’t find the poetry in my language so I’m putting down shitty dialogue that I planned to flesh out when I go back later.
