A "starter castle" that has the potential to be very nice if built on acres of land with a long, winding driveway to get to it but looses it all when it's at an arm's length of the neighbors house.
I can't believe they built four McMansions were the old man Farnsworth's house used to be.

An obscenely large home (usually of at least 3,000 square feet) in suburban America that is almost too big for its use; cheaply built from the inside out; require constant maintanence; stacked so close together in cookie cutter housing developments that you can hear your neighbor on the john; owned and occupied by pretentious, superficial people who care more about materialism and perceived status than actual value, and spend 14 hours six days a week working to pay off the over-inflated mortgage and have no time to spend with each other and experience life for what it is meant to be. The owners literally work themselves to death to pay the mortgage, who also probably struggle to pay off their 20 credit cards and SUV, but don’t have any other time to live a normal life and experience what life is all about. Despite their obscene size, they are occupied by mostly an empty nest couple who think they need like 5 bedrooms and a 3-car garage. They are built by mostly greedy developers who cram as many homes they can for profit.

But things are changing for the McMansion. They are being built less frequently and becoming less necessary as the size of the average American household declines, as the populations ages, and as the economy and housing market go to the dogs. Simply put, McMansions will soon be a thing of the past as people lose their jobs, money, life savings and everything else. In my opinion McMansions represent waste, greed, materialism and comformity, and are also probably one of the reasons the third world and even some ‘rich’ countries hate us.
The McMansion is the epitome of waste in America, and is nothing more than a status symbol for many pretentious suburban Americans who work to death trying to pay the mortgage and keep up with the Jones'.

badly proportioned pastiches of different styles, some are built with attention to detail and materials. But, as the epithet McMansion suggests, they’re just too big—for their lots, for their neighborhoods and for the number of people who actually live in them.

A loser's term of jealousy for a nice house he or she can never afford.
"Did you hear how well Susie's doing? You know we used to all make fun of her in school, well I hear she's got a good job and just bought a beautiful new home."

"Yeah, she's just the type who'd buy a McMansion. I'm happy with my double-wide in the trailer park, it's more 'real.'"

Very similar in behavior to trailer trash...An individual with the outside appearance of successful living (i.e. McMansion or large house, Mercedes in the driveway, trappings, etc)...yet in actuality, conducts his/her life like an animal in the zoo (i.e. heavy substance abuse, extramarital affairs, scandals, slumming, etc.)
Mr. Jones might look successful...but he's really McMANSION TRASH...

Originally a large starter home for someone from the middle class entering into the upperclass status and has arches at the front patio/entry that resembles McDonald's arches.
