"Shooting from the hip" means posting a first draft on a subject with only spelling corrections...no re-writes...or major editing involved, and doing so in an extremely short, non-reflective time frame.
My "carousel" post to Bird of Prey #2722 at JAIL was an original first draft with 15 seconds of spelling edit.
It was composed and drafted in about 200 seconds. Check the time between Bird of Prey's request for a story and the posting of that story...couldn't have been more than 8 or 10 minutes.
