Yeah, I use it all the time too. All my friends seem to know what I am talking about when I mention it, some of them use it too. I probably explained it to them at one point.
Do any other SW sites use the term? I guess we are probably the only place that constantly refers to numerous version of the film, as so have more need of a simple term to distinguish it from other versions. A lot easier than saying, "The outdated, LD transfers that came as bonus discs with the 2006 release".
