What is 6 Up?
A derivative of
Head #1: "6 Up!"
Head #2: "Shit, stash those goo-balls and caps!"
A signal among modern day hippies that law/drug enforcement was near. Named for the six lights that sat atop most old cop cars, it is a way to warn others without implicating oneself.
"6 up, 6 up, in the Dave Matthews tie-dye!"
