Popularized by legendary Seattle pseudo-celebrity, Jack Newton, "jaynoots" has become a word representing excitement. The word is often used as a response to a suggestion or statement, and can be substituted for a traditional response such as "word." Jaynoots is most used in Newton's traditional stomping grounds, such as Madison Park and many Seattle-area private schools.
