running tank

The act of distributing nitrous oxide from a nitrous oxide tank into balloons and selling those balloons to hippies who inhale them and get high....the person who owns the nitrous tank and is making the money by selling the balloons is the one who is "running tank".

John was running tank all night last night, he made like 4,000 dollars.
