Someone consistently terrible at gambling. The most common type of Mahoney is someone who bets on sports & loses approximately 80% of his bets. You do not want to have bet on the same side as a Mahoney. Mahoney is interchangeable with Mush. DO NOT take gambling advice from either a Mahoney or a Mush!!!
I felt good about my Falcons bet until I realized the Mahoney also loves them. That's $200 down the drain.
