a term used by Jason Mraz and
friends to describe someone whose main purpose or job is to bring joy to others.
"Calling her {Tricia} our 'Joyologist' is the way we acknowledge her for the extraordinary job she’s created. Her knowledge of the road, raw food, and rowdy men, partnered with the practice of yoga and
patience empowers her to bring so much
peace, love, and joy to everyone in our touring community and the extended families (including you) affected by our travels." (from Jason Mraz's blog)
