Not that I know of. When the term is used, its *practical* definition is usually something like "so big that, for some implied purpose, it might as well be infinite". For example, in your example of a million lego bricks it is just as impossible to enumerate (in an everyday sense) all the combinations as it would be if there were infinitely many.
