In association football, diving is an attempt by a player to gain an unfair advantage by falling to the ground and, often, feigning injury to give the impression that a foul has been committed. Dives are often used to exaggerate the amount of contact made during a challenge. Deciding whether a player has dived is often very subjective and among the most controversial areas of football discussion. Motivations for diving include receiving scoring opportunities via free kicks or penalty kicks or gaining a team advantage by invoking a penalty card for the opposition. Diving may also be referred to as simulation, Schwalbe, staging (Australia) and flopping.

In the sport of association football, fouls and misconduct are acts committed by players which are deemed by the referee to be unfair and are subsequently penalised. An offence may be a foul, misconduct or both depending on the nature of the offence and the circumstances in which it occurs. Fouls and misconduct are addressed in Law 12 of the Laws of the Game. A foul is an unfair act by a player, deemed by the referee to contravene the game's laws, that interferes with the active play of the match. Fouls are punished by the award of a free kick to the opposing team. A list of specific offences that can be fouls are detailed in Law 12 of the Laws of the Game ; these mostly concern unnecessarily aggressive physical play and the offence of handling the ball. An infringement is classified as a foul when it meets all the following conditions:It is committed by a player ; It occurs on the field of play; It occurs while the ball is in play; It is committed against an opponent.
