1) A woman (also affectionately called a bitch) who challenges the virility and dominance of a man by utilizing verbal abuse and/or by controlling social situations usually controlled by the men.

2) A woman who is so bitchin' and intelligent that most men fear openning their mouth in her presence, much less making a sexual advance.

A generally derogatory phrase applied to a woman who habitually interacts with men in an overly defensive way via verbal insult, superior attitude, and/or avoidance of "conventional" gender roles possibly (make that probably)due to an underlying fear of being taken advantage of or undervalued (ie; not being taken seriously in an age where both genders compete for the same jobs and the like). The behavior is generally unintentionally hurtful and hypocritical.
