A Have-Not is a HouseGuest that has to eat slop in addition to foods voted on by America, sleep in the Have-Not Bedroom, and take cold showers. The alternative is a Have. The status of Have or Have-Not was determined in the weekly Have/Have-Not Competition up until the end of season 15. After that, the HOH chose the have-nots. A HouseGuest may be exempted from being Have-Not by earning a Never-Not Pass.
