Penalty box
When you commit a foul in hockey, you get sent to the penalty box, which looks something like this, a small box you need to sit in for a few minutes. But we guess that when you commit a very hard fall, they just throw you inside of it as punishment.
They don’t want to even pretend that they like you and want you to suffer for the foul you made a few moments ago. So instead of thinking you got off scot-free, you will remember the next time you make a fool, that you don’t want to end up like this again.
