I was having this conversation with some of my bro's earlier.
I guess there's a variety of means to do so.
Like, a leader?
Thinking of Dublin city currently, a dude has the competency, insights, environmental awareness and people skills to come onto the scene, understand what needs to get done, manage the various sub-authority figures to implement suitable strategy relative to their respective divisions - oversee the entire operation making adjustments on spec as needed;
i.e. ultimately amongst all the buffoonery, ass-backwards f**kery and incompetency, make the situation correct, improving the environment, lifestyle framework and quality of life - even for those who would complain bitterly about said changes (perhaps even oppose them), but obviously reap the benefits once they come into effect.
.......
On a more day to day level, I guess an exact definition is more elusive.
There has certainly been the thinking that the "alpha male" is considered the biggest, most masculine looking brute.
Thinking of gyms (which are die-hard alpha male hotbeds), this isn't terribly far from the truth.
Often times size and power can be coupled with a potential for violence basically, and willingness to engage.
Seeing some of the bears vying for position as top dog can be an ugly sight.
.....
Anyways no doubt there's many different perspectives out there on how one may or may not define this... ?
