A contraceptive method dating back to the Vikings.

When having sex with a wench who is unsuitable to bear his children, the Viking pulls out and ejaculates on his knuckles then proceeds to punch the wench in the face.

Mike: so what happened with that chick you took home?

Mark: oh not much...we had sex for a while, but i was too lazy to put a condom on, so I ended up just giving her the old viking hammer...

Mike: Pow! Right in the kisser!

Get the Viking Hammer mug.
When a bag (of any sort) is shat in. The bag will then become a "Viking Bronze Hammer" when it is used as a blunt weapon over the head of any foe, until it ruptures, covering said foe in feces.
Bitch stole my monies, so I gave her a Viking Bronze Hammer and kicked her down the stairs, compound fracturing her femur in eight places.
