Reply #14: I think of a McMansion as this: [View All]

[The Velveteen Ocelot]

A large but shoddlily-built house on a cul-de-sac in a planned suburb, on a smallish lot with little scrubby trees and no sidewalks. The style is faux-French villa, or maybe faux-colonial with big, pretentious two-story pillars in front. It has a three-car garage, and perhaps a swimming pool that takes up the entire back yard. And the people who live there are spending so much on their mortgage and utilities that they can't afford furniture.
