Unsportsmanlike conduct (or unsporting behaviour, or ungentlemanly conduct) describes a kind of action by professional sportspeople. It is when a player or team during the game that is not professional or is offensive. It is not cheating or breaking the rules. Unsportsmanlike conduct is something most players and fans dislike. The official rules of many sports include a rule so that a referee can call unsportsmanlike conduct on a team or player. There may be a fine or penalty.
