Egg Nog

It's quite mysterious. Recently, while at work, I was checking expiration dates on products when I stumbled upon egg nog. I became curious as to what it was. I understand that there are eggs in it, but what is "nog". I read the ingredients and tried to find out, but there was no listed ingredients. They're apparently pretty secretive when it comes to nog. I came home and Wikipedia'd it to find that it was made with nutmeg, butter, cream, and milk. Those must be the components of nog. This aroused the question "Are there any other types of nog?" I launched an extensive Google search and came up with an acronym for Northern Oil & Gas and an alien from "Star Trek: Deep Space Nine". Neither seemed particularly comparable or tasty. If this is the case and there's only one known kind of nog, why is there need to specify which type of nog it is? It seems misleading. Specification like that should only come if there are other options. If there was, let's say, liver nog, A person may need to specify their nog preference. As far as I know, no such nog exists, and because of this I declare that it should be simply refered to as "nog". That is all.
