when getting to a climax during anal sex, the male pulls outs and runs directly towards the female's face. He then proceeds to jump in the air, do a 360, and smash his partner's cheek with his dick so hard that her face craters into the mattress, hence the term "sledgehammer". The male also ejaculates during the sin so it gives an extra sloppiness to the hit. Enjoyable for both participants.
Guy 1: Bro she was so bored with me until I gave her the Norwegian Sledgehammer. We're getting married in August.

A sexual position, modified from the conventional "sledgehammer."

A man will throw the woman's legs over his shoulders, and roll her backwards onto her shoulders so that he is thrusting down with his body perpendicular to the woman's and parallel with the ground.

The balance required for such a feat, combined with the transcendant relaxation state experienced by the woman, is reminiscent of that of a Tibetan Monk.
Man, I just gave my girl the old Tibetan Sledgehammer! Totally on that higher plane bro, so Zen.
