Can men be just as b*tchy as women with each other?

Yes, they are worse than women because they are more ego driven and very little sets them off as most lack confidence and self urance. The fact that being boorish and yobbish is considered an accepted male traits makes their bitchiness even more vicious as its spills unfettered into something called 'male banter' which is pure close to the bone unadulterated bitchiness. Most men are really little boys in adult skin and alpha males are always a threat to them regardless of provocation or not, if you don't behave like them, you immediately become a target.
