A phrase used in Bingo to denote the winning condition when all the numbers on a single bingo card (usually 15) have all been drawn, and the holder of that card calls before the next number is drawn.

Other winning conditions are:
First Five Numbers: the first person to get five numbers on a single bingo card wins.
Any/Top/Middle/Bottom line: the first person to get all five numbers on a single line of a bingo card wins.
and then there's full house.
