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...
