Steam Rich
Term used to describe someone that has immense wealth on the gaming platform, "Steam," more so than their actual real world wealth, and fails to realize that it has no actual monetary value.
Gaben was late on his rent for the third month in a row, but he did not care, because he is Steam Rich, and could give his landlord as many $400 Karambit Fades as he wants, assuming his landlord plays Counter-Strike: Global Offensive, and would accept them as payment.
