A term originally coined by Australian Rock 'n' Roll troubadour Tim Rogers for the bonus disc of You Am I's third album Hourly Daily. After being adopted by mods from the eastern suburbs of Melbourne, the term is now synonymous with wild parties where; 60's music, erratic dancing, and suits so fine they make Sinatra look like a hobo are all common place.
