"the spontaneity of his laughter"
by Robert Rucker October 30, 2007

Taking a risk, living life to the fullest, no plans, "don't think just do". To be spontaneous is to be the most relaxed go with the flow and have fun person, you would never get mad if plans changed you would get excited because than it would become spontaneous.

To go on an adventure without a plan or idea of where you are going or what you'll do next. Basically spontaneity but much cooler.
