One of the best parts of playing competitive sports is the mental aspect and the mind games. If you are able to get under the skin or in the head of your opponent, you can throw them off their gameplan and give yourself an advantage. As mentioned in the prompt, hockey has a lot of different players from different areas of the world which creates a language barrier. There are a couple things we do to get under their skin still. One time we hired a translator and put him behind the bench so whenever we started chirping we would have the translator relaying the information but then they wouldn't relay anything back so it was a one way channel. We also like to load up google translate or something similar and start practicing specific phrases we would say in specific scenarios as a team so we always had fresh chirps to throw at them.
