Ah, yes... maybe we'll just forget that last bit then, right?
(Except that mass and withdrawal lead back to Catholicism, which would of course lead us to Kateri Tekakwitha, who is beginning to seem like the patron saint of Iroquoisiness. Iroquoisyness? Iroquoisyocity? Um....)
Sorry--I even skipped the part about how P-waves, which I'd only associated with earthquakes, are also associated with electrocardiograms.... When I started looking up waves in that sort of medical context, I came across a very interesting meaning for wave motion and mass activity which has to do with sperm motility. Fine, sure, how does that relate to cruft? It doesn't. But lower down on strev's favorites is sperm bank withdrawl (which should probably be withdrawal, btw).
I had gotten P-wave as a random word, and I was surprised that I hadn't listed it already. Then strev made a comment about it, so I found myself looking at strev's profile, where the top favorited word was drunk mouse syndrome (first listed by sionnach). There was no definition here, so I found myself on answers dot com, where the drunk mouse syndrome entry mentioned what happens when a mouse accumulates cruft. It made me wonder whether cruft was one of the words sionnach mentioned when I was lost for word and trying to find a specific name for the stuff that builds up on mousepads and mice. Then, a few hours later, I was reading something on Twitter about temporal lobe seizures as a ridiculously easy explanation for any and all "supernatural" phenomena. The source was a ForteanTimes article, and I couldn't remember whether they were reliable or bonkers (or both). I was looking them up and came across something about UFOs, which led to foo fighters, then to FUBAR, which, of course, led to foobar--about which I learned that it is an important hackerism--along with kludge and, you guessed it, cruft.
