The short definition: A mostly wealthy town in southern Connecticut, United States.
But there is more: Coming from a person who lives in Greenwich, I know it is not the way it is commonly perceived by the public. Many people believe EVERYone in G-wich is a stuck-up snob, that plays LAX or field hockey, that has beach houses, and who lives in a gigantore house. But that is not the case. Although it is true that a lot of people are like this, most of the people are just middle class people, trying to get along in life. Our public high school is filled with preppy white people, but there are some people that are other races that aren't rich. Probably more than you'd think. Also, our school district is very successful in academics and sports. So basically the stereotype of Greenwich, that it is a snobby town filled with rich pricks, is not completely true.
Ryan: When I was growing up, I lived in Greenwich, CT, but I was not rich and I didn't play LAX.
