A sexual ritual that involves a female wielding a battle ax (or any other sharp cutting object) and severing the head of the penis of the given male while the female screams like a crazy drunken viking. If the male does not flinch or bleed, then he is deemed worthy of the woman's vagina.
Dave was treated to the Norwegian slammer by his crazy new girlfriend, Jenna, and he cried like a baby back bitch.

Right before I slipped my penis into my girlfriend's puss, she pulled out a switchblade and sliced the head of my penis off. Now I know what the Norwegian Slammer feels like.
