Sassuality is simply the act of being sassy. It can be defined as a love and desire for verbal power; supernatural confidence; and an unrelenting pursuit of attention. An early sign of sassuality is a burning passion for the last word in every conversation, debate, or discussion. Most sassies can create dramatic phrases spontaneously.
