Not sure what made you think I thought it was a medical term, it's from a flawed understanding of how wolf pack hierarchies work.
Men who worry about projecting strength are often the weakest and most insecure, actual strong men don't worry about whether they appear strong, they appear strong because of what they do.
The alpha beta choads of the internet are some of the saddest most insecure humans I've ever encountered, but you do you boo boo.
Nah, i find that beta males are actually more insecure (and the internet warriors who defend them).
Lets take this game for example.
The MC here is a beta who constantly worries about saving his family from his evil pervy grandad.
If i were in his shoes, grandad would have an 'accident' pretty much immediately after the first conversation.
Instead of cowering, i would do whats necessary to protect my family - ya know, like a normal red blooded man.
I wont go so far as to say i am the pinnacle of alpha-ness like arnold shwarzenegger or something, but i can damn well say that i have some fucking pride.
There is a limit on what is acceptable weakness for men.
There is a general level of masculinity and strength that men should abide by. A metric standard.
Its not fucking rocket science. Its pretty damn common sensical if you think about it.
