However, out of habit people have picked up huge_muscles (currently over 700 posts).
Normally, it would go (small)->normal->big->huge->hyper, however, hyper_muscles is just implicated to big_muscles right now. We could shove huge_muscles between them, but I'd like to gather some opinions on whether that is necessary or wanted at this point, because I'm not sure why it was done this way. My guess is that muscles is one of the older tags and, quite simply, nobody noticed it isn't implicated yet.
