Wild Bill eventually decided he wanted to spell his name with as many horseshoes as possible, because that made sense to everyone. Like someone today spelling his name with pistons or bike spokes. He hooked up with a sidekick named Jingles, named after the sound made by some spurs. Which is just like today, when people have nicknames like "Wiperblade Squeak" or "Muffler Rattle." It's all about establishing a society-wide nomenclature based on the attrbutes of the dominent transportation paradigm.
