Cross-checking is when a player holds their stick with both hands and shoves it into another player. Imagine holding a broomstick horizontally and pushing someone with it.
This penalty gets called a lot in front of the net where defensemen are trying to clear attackers out of the crease area. A little stick contact is usually allowed, but when a player uses their stick to deliver a forceful push, the referee calls it. It is a two-minute minor and can be a major if it causes injury.
