A penalty called when a player takes more than three strides without gliding to make a hit or leaves his feet to make a body check.
Charging can be a difficult penalty to see in real-time. The league is continually instructing officials to call this kind of penalty as it often leads to injuries. Although you used to see this penalty rarely called, you see more and more of it today.
It could also be called when a player body checks a goaltender when they are in the crease.
