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.
Guy 2: Whoa, congrats, man!

Get the Norwegian Sledgehammermug. The Norwegian Dip is the sexual act in which the male counterpart dunks his penis into a toilet and inserts into a nearby crevice. (note that the male only inserts his shaft, not his balls)
