Timewasting
This article refers to timewasting in a sporting context. For wasting time in a more general context, see Procrastination.
Timewasting (or time-wasting) in the context of sports refers to the actions of one team which expend time, but do not otherwise have a tactical purpose. This is usually done by a team that is winning by a slim margin (or, occasionally, tied) near the end of a game, in order to reduce the time available for the opposing team to score. The term "timewasting" is generally reserved for varieties of football, though the practice exists in many other timed sports, including basketball, gridiron football, and hockey; timewasting in these sports is often referred to as running out the clock.
