1 definition by Chadwick Bradford Simmons, IV
A town in upper Westchester, similar to Scarsdale, but for the more elite and less nouveau-riche. Formerly more popular among the privately wealthy before names like Larry David, Jeff van Gundy, and of course, the Clintons came to town.
"We looked at houses in Scarsdale, but it's just too jejune for our tastes. I moved to Chappaqua instead."
