ILL-LEGAL

I've noticed that my local radio station has taken to pronouncing eighteen-year old girls "legal" during their birthday announcements, as in, Birthday wishes going out to Jane So-and-So of Jamestown who turns legal today... Is it just me overreacting or is that rude? It's not like I'm listening to Howard Stern -- this is a little radio station in the middle of the cow patch I call home. I realize that some magazines and websites have countdown clocks ticking away every second until Hilary Duff's or Lindsay Lohan's respective eighteenth birthdays, but when did this kind of crudeness become mainstream?
