A badass knows what the fuck is up.

Awesome to an extreme level, thereby leveraging unquestionable authority.

Badass is defined in one word: Caravaggio.
Son of a bitch was the most bitchin' painter around 1600, and he brawled his way around Italy. He was so badass, the Pope fucking pardoned him for killing some dude in a bar, just so he could come back to Rome (he had been on the run) and paint for some Renaissance-era mercenaries who happened to just love epic art. Damn, son. Damn.

One with very large ego. Allows them to be direct and efficient in all they do. Also allows for a disregard to the standards of others, resulting in a personal code thats badass. Additionaly, one who disregards power in numbers and will often kick the shit out of multiple lesser opponets who are caught defiling this personal code. (a trash talker, women beater, dis honering family, ect.) They are often quite but out spoken as what they say is direct, wise, and simple. one who dosnt need to pretend to be badass because they just are, and they know it. However badasses gain power with into music.

The true American male. He is so insecure that it shows anytime he does anything, whether it's ordering yet another drink, buying a car way beyond his means, or treating women like shit. He is always looking for a fight, but if anyone stands up to him he whimpers away as the coward he is. He thinks that shouting at and beating women is the way a "man" handles these matters, and will sexually harrass any woman, regardless of age, in an effort to repress his homosexual desires.

A badass thinks and does whatever he sees on TV or hears on the radio. He wears whatever is advertised, and he drives a car meant to distract from his miniscule dick and inability to please a woman. Since he has not yet evolved independent thought, he does whatever the media tells him to. His "style" is a tasteless combination of whatever is popular at that given moment. He may have a Harley or a Corvette, or some other set of wheels that "gives" him style, because he sure as hell has none! All in all, the consummate loser.

someone who can just sit and radiate badassery without yapping like a little girl 24/7 about how badass they are.

Generally refers to a male. Confident, secure, uninhibited, so cool it hurts, hardcore, independent – all in one. I guess the character of James Bond is expected to be badass.
Sometimes referred to a woman. Means being down to earth, daring, confident unafraid of challenge (not intellectual but the challenge of real life experience – sports, extreme experiences, edgy actions). I guess they refer badass to a woman who looks quite tender and feminine so that they do not expect her to keep her senses facing a challenge. maybe a badass woman is an attractive female who behaves unexpectedly confidently in unusual situation.
