Kristen, there's a reason for the "soccer mom" thing. It has been catching on for many years, starting with the little ones. Now that I have a Brit for a son-in-law, I am learning to call it football! Although I heard on CNN or somewhere the other day that the term was "soccer" coined by the Brits! We already had "football" by the time it hit here.
I forget where I was 4 years ago during the World Cup, in Europe for certain. Flags hanging out apartment windows everywhere to support their teams!
