A single jump bid made as an overcall eg 1♠(South)-3♦(West) or 1♣(South)-2♥(West). Traditionally a jump overcall showed a strong hand (similar to opening one of a suit and rebidding three of it) but it is becoming increasingly popular to play weak jump overcalls (similar in strength to a weak two opening).
