I've heard the word, Father Steve. When Jules Verne was building the prototype submarine for "Captain Nemo" to pilot (he wanted to be able to write excellent descriptions for his readers), for the longest time he couldn't seem to get the crankshaft to stop trying to jump out of its mountings. Finally he got it to turn smoothly in place like it was supposed to, so he named the sub Juddernaught.Sorry--I know I've fussed about trying to keep Q & A for serious word discussion, but I just couldn't resist this. Won't happen very often, I promise.
