While practicing, I came across a new technique. At least, I think it is new. I call it a slap/strum, where I slap a string while *simultaneously* strumming a chord. I do this by making the devil-horn sign with my right hand while flicking my middle and ring fingers for the strum. While flicking, I slap with my thumb. I don't know if this is new or old hat, but, I thought I would share.
