Currently, how I do it is...
Universal - One universe of finite or unknown size
Universal+ - An infinite universe, with possibility of it going higher
Multiversal - Any multiverse that is finite or has an unknown number of universes
Multiversal+ - An infinite multiverse, if not higher
Massively multiversal - The catch-all term I use for anything from multiple multiverses & higher orders of infinity and so forth
Also while we're here, what is the difference between an alternate timeline and an alternate universe? I need this described to me in great detail because the two often seem interchangable (along with 'alternate dimension' and 'alternate reality').
