When I'm in a good mood and playing well I'm pretty chatty. I tell myself "next shot, next shot" after a save or goal, just to settle down and focus on the next shot. I'll also remind myself to take a breath, give the posts a tap, or give the stick some love after a shaft save (inspired by MAF - https://streamable.com/65qah)
If I'm feeling really good/at a good group game I'll yap at the players. A good glove save will be a "oh hey, do you want this back?", if a player falls or skates into me I'll say "oh you looked pretty good out there. Thought you could skate, too", or complimenting someone's hair/stache if they get a little too cozy on a screen.
If I'm in a bad mood or playing poorly or if I'm playing really well and in the zone, I don't say anything, haha.
