Expressing disappointment

This is about the  phrase "boom...aw...shitty" which came about like this:
On the 4th of July in Woods Hole we used to go out to Nobska to watch the Falmouth fireworks. You could see the fireworks but you were too far away to hear the explosion. Getting into the habit of supplying the sound artificially by saying "BOOM!", it was possible for the firework to be seen, shouted at, then be disappointed by, all in sequence. I guess the fireworks have gotten a lot better since then.
