This phrase originates from Episode 15:

Early on in the touring life of the Long Winters, ”Extra meat for a dollar” was a joke among the other guys in the band. John was always the last one to sit down because he was parking the van and when he would walk up to the table they would all be looking at the menu and would have searched it to see if it said ”Extra meat for a dollar” anywhere on it. They would be like ”Hey, John! Extra meat for a dollar!” - ”Double it up! Double it up!”
