Lunch Money

In sneaker talk, the term "lunch money" is used when a sneaker is sold for very little profit, i.e. the sneaker is sold for a little over it's retail price (hence "lunch" money, typically because it is a small sum of money you would buy lunch with). This sum typically varies between 5-20$.

Person 1: I sold my yeezys for 235$ yesterday.
Person 2: but you paid 220$ for them! That's lunch money profit.
