For writing it conventionally means means writing words without stopping to plan or edit, no corrections allowed, the rule is you just have to keep typing, no matter what.

Since writing is very hard and rewriting is comparatively easy and rather fun, I always write my scripts all the way through as fast as I can, the first day, if possible, putting in crap jokes and pattern dialogue—“Homer, I don’t want you to do that.” “Then I won’t do it.” Then the next day, when I get up, the script’s been written. It’s lousy, but it’s a script. The hard part is done. It’s like a crappy little elf has snuck into my office and badly done all my work for me, and then left with a tip of his crappy hat. All I have to do from that point on is fix it. So I’ve taken a very hard job, writing, and turned it into an easy one, rewriting, overnight. I advise all writers to do their scripts and other writing this way. And be sure to send me a small royalty every time you do it.
