An alpha male is a dominant personality, a leader, confident. It refers to hierarchy among social animals. The phrase derives from academic studies. I'm sorry, but I had to look up androcentrism in my dictionary. I would say the concept of alpha males is simply an academic subject that may have been subsumed by a popular notion of idealized male behavior. This may imply androcentrism.

Alpha-male is the lead male in a group. The leader, the guardian, usually the strongest. Alpha meaning first.

A dog can also be an alpha dog. They lead the pack. Just as a dog can be nurturing and tender with puppies, it can also attack another dog or animal if it threatens that puppy or dog. There are some men who are more geared towards being in charge. It can be nature or nuture, I suppose, or in other words, biological or a societal response.

tks Craig, tks for sharing so interesting story~~~~

Alpha male, like the strongest gorilla in the jungle, the one that is the strongest and who gets to mate with the females. It's slightly illustrative when used to describe humans but it does also mean the same thing, the biggest, most muscle bound male, that the lesser/weaker males have to follow/obey. But it can be something of an insult too, "Tom is too much of an alpha male, to ever be able to consider anyone else's feelings, he's too aggressive and not really sensitive or intelligent enough to do his job properly". "Alpha" is from the Greek alphabet, and it is the same as "A" in English (A,B,C,D.....etc) or in Greek Numerals it means Number 1. So "Number One Male" - or if there were numbers attached to importance or relevance in the group, the first male would be the most important, and say the 1000th male would be the least important (like me hehe). I'll never forget laughing when I saw 2 male gorillas fighting on the television, to earn the rights to mate with the females, and whilst the biggest gorillas in the group were fighting to the death, the little skinniest gorillas were having sex with the females behind some trees hahahaha Sometimes Alpha men don't win the competitions haha
