As a Level 15 message board arch-nerd, I love that word, because it's a sort of two-fer: it suggests "noisy", which is really what I'm getting at, but actually means "annoying" --- "noise" and "annoying" having apparently different roots.

I felt like my response was dispositive. I'm telling you straightforwardly that's not what he meant, and I have good reason to believe I'm right. Your rebuttal actually ignored the substance of my comment and instead launched into a tedious semantic tea-leaf-reading exercise.

"Noisome" seems like the right word. :)
