Fighting in ice hockey is an established tradition of the sport in North America, with a long history that involves many levels of amateur and professional play and includes some notable individual fights. Fighting is usually performed by enforcers, or ''goons''--players whose role is to fight and intimidate--on a given team, and is governed by a complex system of unwritten rules that players, coaches, officials, and the media refer to as ''the code''. Some fights are spontaneous, while others are premeditated by the participants. While officials tolerate fighting during hockey games, they impose a variety of penalties on players who engage in fights.
