Pro-D day - not a tough one, but on Ontario we called it a PD day and if you use that here, people are confused.
Stuffies - again, not hard to understand, this is what we call stuffed animals like Teddy Bears.
Gym Strip - what students wear for gym class, e.g., "go throw on you gym strip and do 10 laps". This one makes no sense to me.
A sunrise is still called a sunrise though.
