OnTheWayOut: Maybe it's lost in culture.
Yes you are right. Here in NZ we do not use the term 'flash house' to refer to a brothel. It simply refers to a flashy house, an expensive house usually built or purchased to show off ones wealth. This is what karter was referring to. An expensive house. So clearly the truth is stretched when the wrong impression is given by relating rubbish at some assemblies or conventions.
