I find language fascinating. Names for groupings of animals is strangely logical. Most people are familiar with certain terms, such as a murder of crows and a congregation of baboons. How about . . . A streak of tigers. A shiver of sharks. A covey of quail. A passle of pigs. A chine of polecats (that's skunk to you non-country folks).
I picture someone sitting on a wrap-around porch one evening, sipping a frosty lemonade, the condensation rolling off the glass, and a scourge of mosquitos assails them. Right there and the, the term is created, applied, and recorded for posterity.
