This one sounds like one of the words my five year old brother made up but what it actually means is:
1. an extraordinary or unusual thing, person, or event; an exceptional example or instance.
1900–05, Americanism ; origin uncertain
2. an annual music festival featuring popular alternative rock, heavy metal, punk rock and hip hop bands, dance and comedy performances, and craft booths. It has also provided a platform for non-profit and political groups. The music festival hosts more than 160,000 people over a three day period
