Milk chugging

Milk chugging, or the gallon challenge or milk challenge, is the "sport" of consuming a large amount of milk within a set period of time. Although procedures vary, the general requirements are that a person is given 60 minutes to drink one US gallon (3.8 L; 0.8 imp gal) of whole milk without vomiting. A gallon milk jug is a common size of milk container in the United States.
