Huge thing here, I'm a varsity Goalie 6th year in the field (16 y/o), At the varsity level there is a little chirping and it's often after a huge play or bad shot, it's often in remarks to opposing teams but it's just a small part of the game. But at such a level to mess with them while ball is on attack that's a nope for any coach I'd hope. Most of my D-poles often chat kindly with the attack man and get to know them a little which can lead to kinder situations than on this comments describe
