Black's Law Dictionary
A bid made after a judicial sale, but before the successful bid at the sale has been confirmed, larger or better than such successful bid, and made for the purpose of upsetting the sale and securing to the "upset bidder" the privilege of inking the property at his bid or competing at a new sale.
