There comes a time in first drafts when your mind goes mad, but as mad as gets, it always spews out the right thing. Don't go back into those passages soon after, especially if you're writing something that is new and boundary-pushing for you. If you do, an inner voice will emerge and make you question everything you wrote. Is it okay? Is it proper? Is it something a huge audience will enjoy? This voice doesn't know you and it doesn't know your potential. This voice is a buttfor.
And what is a buttfor? It's for shitting all over stuff.
Trust your instincts on a first draft. During revision, things will change, but always remember the voice of madness. It is passion. And it is true.
