The fingers in the air is a way of saying you need a ticket like at phish or the dead, or if you hear "i need a miracle" they mean they need a ticket to the sold out show that they are in the parking lot of. I buy my tickets beforehand, so I never need a miracle.
Yea, and I know phish isn't a band anymore, and maybe the dead aren't either, I was just using the names as examples. (One person I know corrected me on saying "if you go to a phish show...")
