canadian jackhammer

A Canadian Jackhammer is when you are 69ing a girl while you (the male) are standing. When you are about to ejaculate, you drop her on her head.

We got pretty freaky last night. She ended up with a concussion after we tried that Canadian Jackhammer.

Sicilian-Jackhammer

When a man is having oral performed on him while hes standing up, at the climax... he pulls out his cash and prizes and cocks back like hes ready to do a 360 and smacks his partner in the side of the face with his rock hard penis. (being during the climax the female may have the misfortune of having a steamy load shot through her hair and face)
