Who or what is it/he?
According to the Urban Dictionary an Alpha Male is:
The term ‘Alpha Male’ can be defined in both a classical and modern sense. The classical definition derives from the animal kingdom and represents a physical form of dominance over other males. The alpha male lion, for example, claims sexual rights to all females, fights off other male lions to enforce it, eats first after every hunt and dominates a vast territory of land for hunting rights.
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 their ‘hunt’ for new women, such as local nightclub scenes.
Older alpha males, however, will evolve the classical traits of strength, intimidation and dominance beyond the physical by gaining power over men through their 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 similar capabilities over others in their 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.Mike Tyson was the alpha-male of boxing until Evander Holyfield defeated him, while Bill Gates is currently the alpha male of the software industry.
How about Alpha Males in BDSM?
As I pointed out before the film “Fifty Shades of Grey” that is so popular nowadays shows us an Alpha Male. But I agree with Dennis Najee (that wrote some great books as well) that a true Dominant has control over his own life first and foremost.
