A ballerina is usually not considered to be BAD, but beware. What you DON'T see is what will get you. Part of being BAD is the ability to carry oneself without showing off. The Twelve Postulates of Being Bad explain the twelve points of the BAD lifestyle. They are mostly common sense, but when assembled as a collective entity, they become a guide to a lifestyle up and beyond normal social expectation.
BADness is an aura which surrounds oneself.
It shines like a light around you and all of what you do. Others will know that you are BAD by sensing this invisible aura. Physically showing off always leads to disaster. One of the ways to tell whether someone is BAD or not is to see if he is or likes to show off. Never break BAD on anyone unless they have invaded your space.
