A breakfast ball is a golf term that refers to a mulligan given on the first tee as a "free" extra shot. It is typically used during an early morning round, sometimes before breakfast. A mulligan is a stroke in golf that is played again without penalty, usually after a poor shot. The term "breakfast ball" is often used interchangeably with "mulligan". It is important to note that a breakfast ball is only supposed to be for the first tee shot of the day.
