Because everything's a damn acronym now. Nobody can be bothered saying "Major League Baseball"; it's MLB, NFL, url, FBI, CIA, IRS, IRA, blahblahblah. Going by the commercials, there's one for low testosterone, too -- "low T".
And I'm already annoyed by "frozen precip". 'Smatter, frozen precipitation is too many syllables when snow has turned into "snow showers"?
Argh. Curmudgeon, that's me.
