I’ve heard it used in debate, where it means something similar. It can also be called “spreading.” You raise so many different objections to the opponent’s argument, that they can not possibly answer them all in the time alloted.
I saw the term used here today, and am not sure it was used accurately. It seemed to mean just answering again and again and again, which, as long as you are adding new information, and you back up your arguments, does not seem to me to be a problem. People argue as long as they can tolerate. There’s no social convention I am aware of that says jellies should hold back.
But you never know. A newbie may have brought us a new tradition—a way to cut off debate before it bothers everyone else. I know a few people who would use that on me, for sure!
