Okay, so scuffing a penalty mark might be seen as "unsporting behavior," which could potentially lead to a caution from the referee.

I should provide a quick translation, explain its implications briefly, and see if they want more context or the original source. It's also a good idea to note that this is a light-hearted remark, reminding them that scuffing goes against the spirit of the game and may result in a caution. Let’s get that sorted!
