Are regular straight men beta males or sub-alphas?

I really favor the idea of a “sub-Alpha” class. I’ve definitely encountered (and know) of straight Men who are absolutely not Alpha, but are also not beta (or submissive). In a broader sense, “beta” simply means ANY male who is not Alpha. But there is definitely a sliver of the beta class who are not submissive enough to warrant the full moniker.  

I might mull this over a little bit and see if there’s a suitable name for this class. Thanks for the excellent question!
