That is one of the problems with people that get upset about what people call things. A lot of the time the cute little names like Golf Ball, Glider, Fast Track are either a result of confusion and lack of enough exposure to have committed the real names to memory or like myself, for my own amusement I tend to label them with different names. IASW for example is commonly referred to, by me, as "the boat ride to insanity". I can assure you that I know the proper name, but, I like to have fun with it. I suspect that many of the overheard names used within families were the result of someone, probably a child, misnaming it and it stuck. I know it bothers some people, but, I have no idea why.
