A vow taken by someone that they will not beat off (masturbate) until a goal that they have set for themselves has been achieved. It is a method of motivation, used mostly by athletes.

Also a great idea for a sexual competition with a high male to female ratio; in which female competitors compete in events such as the "Man Milk Chug" and "Queen's Cup" Queens Cup could be described as similar to the Man Milk Chug, however using lesser fluid volume.
Stacy, did you see the hotAsian chick win the Man Milk Chug event in Unbeatable Bukkake?
