What is crosscheck in hockey?

Answer 1

Cross-checking is never permitted and if caught by an official, will result in either a minor, major, match, or game misconduct penalty depending on the severity. If the cross-checking is a penalty other than a minor penalty, then an automatic fine is assessed and the player may be up for a possible suspension.

Answer 2

A crosscheck is when a player holds their stick in front them (how they would a shopping cart handle) and pushes another player on the opposite team with their stick, often across their back. This will get the crosschecker a 2 minute penalty for cross checking.
