Well, if I remember I will come back with explanations.

"The crease" is not actually default-obscene, it's the bit right in front of the goal, just off the top of my head. The "this is probably about sex" algorithm is generally right on but can lead one astray.

"Five hole" is between the legs. Not default-obscene! It's talking about shooting the puck into the net between the goalie's legs! (The other spaces for scoring around the goalie's body are also numbered.) But...it does go there.
