Basic idea is just to stand up for your dignity and stand by your masculinity. I hear guys all the time get disrespected, sometimes lightly, and sometimes the chicks real nasty, majority of the time(90%) the guy says nothing to her and either agrees with the disrespect or they say nothing at all. Ive even seen guys get physically bullied and even hit/punched(not talking love taps or a touch slap on the forearm) and the guy just takes it....
Not alot of men show any leadership or control of themselves so the woman in the end takes over and runs things. AND whats really sick, is woman sense this, if they know they can overpower some guy they will do it....then the guys that the women know are strong and dominate they WILL NOT EVEN ATTEMPT such Sh1t(typically).
Then on the other hand you have to realize your working against a slight curve, many girls dont know any better and just run their mouth, and thats when its time for you to put them in their place...
And keep in mind, dont lose your cool while standing up for yourself, whatever can be said can be said calmly and in a proper manner.
