And according to The Hockey Writers, it’s just the same as when he was in Washington and had a ‘safe word’.
“A couple of the guys gave me a safe word if I was getting too excited,” Schmidt said. And what exactly was that word? “That’s going to stay with me. Brooks Orpik, if you ever get a chance, he’s the one who originated it. Sometimes I would just get too excited, and he would just go, ‘Whoa, whoa, whoa, take a deep breath, just relax a little bit.’ ” (source)
Edit: Apparently the safe word was... penguin.
“"He obviously has a lot of energy, right?" said Washington defenseman Brooks Orpik, who was paired with Schmidt some last year. "But he's fun. Over an 82-game schedule, you need guys like that. . . . There are days where you come in, you feel tired. Once you see him, you don't feel very tired anymore."
But Schmidt's motormouth can't run constantly over six months of a season. When it got to be too much, the Capitals developed a "safe word" that, when uttered, signaled to Schmidt to calm the bleep down: "Penguin."
"I don't even know how it started," Orpik said. (source)
