There are many kinds of badasses. A badass can be a good guy or a bad guy, a man or a woman, a brawler or an acrobat. One of the main traits of a badass is the ability to kick lots of ass. However, being able to kick ass does not make you a badass. Badass is a frame of mind. A badass gets shit done, and does it in a really cool way. Badasses take down anyone who crosses them without even thinking about it. The only thing that can stop a badass from reaching his or her goal is death, but some badasses don't even let death stop them. A badass generally lets his or her actions speak for themselves. Badasses live by their own rules.
"Did you see that? He just killed all of those ninjas without breaking a sweat."
"Yeah, he's badass."
