Bacon... What can be called bacon?

One way to get the bacon boys riled up is to tell them you're bringing bacon and come with Canadian bacon... something they classify as a wonderful pork product, but not bacon. So what makes bacon bacon? Is it the curing process, is it where it comes from on the pig, is it the smoking or is it all of these, or is it something else? I never really thought about what made bacon bacon, it was always there for me in the store or on my plate at breakfast, I guess I've always just taken bacon for granted. Here is a site though that defines the different types of bacon which I promise to learn. Let me pose the question to all you out there: "What makes bacon bacon"?
