I just number them. e.g. "4 thousand billion". <i>Little Billy Sands</i> we call him.<p>But seriously, I have given them descriptive names - inspired by the supplier of meat to MacDonalds in Australia called "The 100% Australian Beef Company". I figured it was good for googling, and informative. Also reminded me of Humpty Dumpty (<i>my name means the shape I am</i>). And it worked.<p>Though I note most people go for clever and/or zany names, with creative spellings (so they be trademarked). An amusing "story" to explain a clever name can operate as a vector for word of mouth: by passing on the story for entertainment value, you also pass on the name. It's kind of like product placement, where the story is the movie. An example is <i>GNU</i>. It can also operate as an in-joke, creating an artificial elite.
