The phrase soccer mom broadly refers to a North American middle-class suburban woman who spends a significant amount of her time transporting her school-age children to their youth sporting events or other activities.
Soccer moms received so much attention during the election that the American Dialect Society voted “soccer mom” Word of the Year for 1996. The columnist Ellen Goodman of The Boston Globe called 1996 “the Year of the Soccer Mom.” An Associated Press article named soccer moms – along with the Macarena, Bob Dole, and “Rules Girls” – as the four phenomena that will be forever associated with the year 1996
