support money
Money that, alone, would not be able to purchase something at a store or event. However, is used when a friend barely doesn't have enough money and needs those few extra dollars, or cent, to buy that clothing item or food that they've been looking at.
Support money can be completely worthless when you're shopping alone, but when
it's you and your group of buds at the baseball/football/basketball/hockey game, it can really come through and
nab you that extra set of nachos.
