Plucking with two or three fingers at once

This isn't about playing fast and alternating fingers - quite the opposite. Do any of y'all ever pluck a single note using two or three fingers? I found myself doing this without thinking on BG after a few months of only playing the DB where this kind of technique is quite normal. It made for a nice fat tone but it seemed like a rather inefficient and tiresome way to play fast. Is this something worth practicing or a bad habit that I should get rid of?

Not often. However, it would be a good way of slowing down and encouraging to think about constructing lines with a DB mindset; if I'm trying to to that, I more often switch to using my thumb and palm muting or to plucking the strings over the neck, which is another way of getting a very fat, woody sound.
