What is an alphahole?

For many years, I never read a romance book. When I did, I had a few years of never encountering what many call an alphahole. Then I met many of these so-called alpha heroes. To me, these alphaholes aren't truly alphas. They're toxic, as in toxic masculine.

Here's a definition of toxic masculinity from an article written by Alia E. Dastagir. "[T]oxic masculinity, the stereotypical sense of masculinity that embodies behaviors, such as denying help or emotions, which psychologists and sociologists say are harmful to men and to society. It's the things in our culture — from toys given to movies watched to messages parents consciously and unconsciously send — that tells boys and men 'being a real man' means repressing feelings and consistently demonstrating strength and dominance." 

So for purposes of this blog, I'd like to call heroes who are toxic with their masculinity simply toxic or toxic masculine. I feel calling these kinds of heroes alpha gives the word alpha a bad meaning. 

But what do you think?
