Icing: When the defensive team shoots the puck from behind the red line into the opponent’s offensive zone and across the red goal line, icing is called. The puck is then taken back into the defensive zone for a face off. In some leagues the puck must be shot across both blue lines for icing to be called. The linesman or referee may "wave off" icing if they feel the players in their defensive zone could play the puck.
Illegal body checking: In no-checking hockey, a two minute "roughing" penalty will be assessed whenever a player impedes the movement of a puck-carrying opponent by pushing the player with the hands or arms or deliberately contacting him with the shoulder, hip or any other part of the torso.
There are instances when considerable body contact between the puck carrier and an opponent may occur that will not be penalized, provided that there has been no overt hip, shoulder or arm contact to physically force the opponent off the puck. Likewise, there will be no penalty assessed if the puck carrier unsuccessfully attempts to skate through too small an opening between the boards and a stationary opponent and a collision occurs, unless there has been an overt action to body check the puck carrier.
Deliberate body contact on the part of the puck carrier may also be penalized under this rule. In order for a body checking penalty to be assessed, enough contact must have occurred to impede the movements of the puck carrier.
Intentional offside: An intentional offside is called when the referee feels that a team caused the offside to obtain a stoppage of play or when the puck is shot into the offensive zone and other offensive players are below the hash marks in the offensive zone. The face-off takes place in the offending teams defensive zone.
Interference: A two minute minor penalty will be imposed on a player who interferes with or impedes the progress of an opponent who is not in possession of the puck, or who deliberately knocks a stick out of an opponent's hand or who prevents a player who has dropped his stick or any other piece of equipment from regaining possession of it.
Kick save: When a goaltender kicks an incoming shot out of the net it is known as a kick save.
Lactic acid: Lactic acid builds up in the muscles as a byproduct of oxygen use and can cause cramping. Aerobic conditioning can prevent excessive lactic acid build up.
Left wing lock: The left wing lock is a defensive strategy in which the left wing drops back to play parallel to the defense when the other team begins their breakout.
Lift pass: A lift place clears the ice by a few inches on its way to another player. It is used to pass over an opponents stick
Line: A group of players who play as a unit is known as a line. The center and the wings are considered a line as are a defensive pair.
Linesman: The Linesman is the official(s) that stays next to the blue line. The linesman calls offsides and icing. The linesman also drops the puck for face offs. All other penalties and calls are made by the referee. Linesmen are also sometimes called assistant referees.
Low in the zone: When a player is between the goal line and the hash marks on the face off circle they are positioned low in the zone
