2. The dudes that pick who they want on their shitty teams in gym class. Arch nemesis of the nerd-people.
2. Greg, the alpha male, picked Scott for his dodgeball team; everyone thinks it's because Scott is well-built, but really Greg is just a closet homosexual and will jerk off to a picture he has of Scott when he gets home. He will then watch Sex in the City and drink cranberry juice.
In a modern/human sense, younger males (teens, early 20s) will subscribe to the classical form. Like a lion, they will often be the strongest, most intimidating, hit on all of the women beta males want, are usually the first to have new sexual experiences and often dominate a set territory in thier 'hunt' for new women, such as local nightclub scenes.
Older alpha males, however, will evolve the classical traits of stength, intimidation and dominance beyond the physical by gaining power over men through thier very means of living and professional reputation. A powerful business executive, for example, will hire, promote, demote and fire others according to how well they serve his own interests. Rock stars, famous actors and other individuals of 'power' hold very simular capabilities over others in thier respective professions.
Younger alpha males who cannot mature into the modern form will usually cling to the classical form of alpha-maleness for as long as possible.
2) any person with a dominating personality, causing the assertion of or struggle for leadership in almost any situation.
