What comes after a gazillion?

Here is the problem. There is really no such number as a gazillion. It is an expression used to mean a really big number. For example, we say that are a gazillion reasons not to do homework right now and one of them is to answer really fun wiki answers questions and we know there are a gazilion of those to answer. So there is nothing that can come after a number that does not exist. Another example of this is a bazillion which also is not really a number. One thing is sure about these non-numbers, if you answer a gazillion-billion wiki answer question you will know a lot, and you will be a ruby contributor. You may even win some wiki prizes!
