look up any word, like eiffel tower:
An old Danish word for being a viking and having been eating mushrooms all fucking day just to rape some women and cattle. Also the name of a pretty awesome Danish band.
"Hey wanna fuck my sister?"
"Relax dude, I'm not going bersærk yet"

In Danish:
"Jeg skal bare have to hajtænder"
"Desværre, vi har kun tamponer, der får dig til at gå bersærk"
