I think I got it. First I tried some combinations in Esperanto, and was very close to a nice result of "vibrating light," but the available vowels didn't help me get the suffixes right.
So I tried something different. Taking the letters I and V to stand for the Roman numeral four, I arrived at this:
aim4blur
Meaning, "point your attention towards things unclear," the unstated next action being, "shoot."
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
