Someone who buys sports cards or trading cards with the sole intention to sell them for a profit. CardBros are known to gloat about recent purchases, wait in line at stores for hours to buy boxes they plan to sell for triple what they paid, and claim a player or team is for their collection and then sell them the first chance they get. A cardbro is considered a detriment to the hobby.
