That was what we called "Lee and D" after Lee G., the GM in question. he was as a player a True Munchkin, and as a GM the Railroading Showoff (i.e., Follow my Plot, and Ooo my NPCS are SOO MUCH COOLER THAN YOU!).

Of course, the best example to tell to other people is to point to Final Fantasy VII. "Imagine THAT as a FTF game. Note that they don't even try to HIDE it. They use the railroad metaphor IN the game."
