shoveling the crease

To have sex.

Comes from the hockey term to clear away snow from a goaltenders play area.

Q: "Dude, did you catch the epic Kings beatdown of the Ducks last night?"

A: "Nah, I had this cute puck bunny come over and I spent the whole night shoveling the crease! Damn, it was good, but I hope I don't get boner's remorse - she's done like half the NHL."
