"image quip"
Of course, when I google "image quip," I see it's been used before, but only by about three people and none of them to refer to the above-described doohickeys.
I created these image quips as a form of rather shameless self promotion, hoping they'll catch on like wildfire on message boards across the globe, skyrocketing me and my little grammar books to international fame or a least into one more printing. So, the-forgive-the-shameless-self-promotion qualifier now stated, here they are. Use them liberally.
