In ice hockey, short handed refers to having fewer skaters on the ice during play, as a result of a penalty. The player removed from play serves the penalty in the penalty box for a set amount of time proportional to the severity of the infraction. The penalized team is said to be on the penalty kill (PK) while their players are in the penalty box. The opposing team is usually referred to as having an "advantage" until the penalized player returns to play. This situation is often called a power play for the opposing team, due to the increased likelihood of scoring during this time. If the team with the advantage scores a goal while the other team is short handed, the penalty is over, unless it was a major penalty.
