An horrible historical note: the term fur-BLAM came upon us one day whilst
discussing less-than-civilized hypothetical sports, in this case hunting
squirrels with shotguns. The conjured image of the post-shot
inwardly-rotating torus-shaped cloud of disembodied fur...ugh, icky. Waste
of a friendly squirrel. Bottle-feeding the little beggars into maturity is
much more rewarding. The macabre aspect has faded, but we still remember
sometimes. We use it to describe explosive clouds of fur, now.
