A group of fucking excellent guys, over the age of 30, who rave at every possible opportunity, usually staying up for 3 or 4 days in one go. The Junior Rave Kru (under 30s) are the totally shit precursor to the much better Grandpa Rave Kru.
Raver #1: Who's that guy busting the incredibly shit dancemoves over there?
Raver #2: He's a fanny from the Junior Rave Kru.
Raver #1: Just as well the Grandpa Rave Kru will be here soon to kick the fucking shit out of them.
