SOD
n.— «In December 1996, inspired in part by Mr. Randall’s well-publicized late fatherhood (his wife was 26 at the time), I wrote an article for The New York Times about men having children at a stage in life when their peers were usually contemplating a move to Florida or their next cardiogram. One proud papa dubbed them start-over dads, or SODs for short.» —“He’s Not My Grandpa. He’s My Dad” by Thomas Vinciguerra New York Times Apr. 12, 2007. (source: Double-Tongued Dictionary)
