I haven't played ice recently, but for ball hockey...
Players trying and trying and trying to deke around the entire team because it worked once 8 months ago.
Players who won't sub, but don't back check at all and don't even go hard on the attack. Just hang somewhere, don't move and can't shoot. It's just for fun and something to keep active, but I will just tell people to get off if they're doing shit like that.
And the one guy I play with, whether he's in nets, or a defender and I agree with him, but don't get as pissed are people who don't cover the back door pass. Players come back and stand like 3 feet away from the guy on the back door.
