look up anything, like your first name:
1. FLÆ
FLÆ is a shorter version of "Fylla" who means getting drunk in Norwegian.
Instead of shouting out "Fyllaaaaa", you can just scream FLÆÆÆ.

Many people claim they invented this word, but its origin is in Oslo. More specific at Grefsen by The Grey One(HG) and his friends.
Tonight I am going at FLÆ!
Last nights FLÆ was awsome!
2. BIFMUF
BRA I FYLLA, MEN UT TIL FROKOST

Norwegian, means "Looks good when you are drunk, but have her out before breakfast"

Often used after a "one night stand" when you realise that you had sex with something that looks like a Hipopotamus :P

Hun som ble med meg hjem i natt, var skikkelig BIFMUF ass...
3. luremus
common Norwegian word for dicktease or pricktease
Norwegian: Jeg møtte en deilig jente på fylla i går kveld og hun ble med meg hjem og alt, men så viste hun seg å være heftig LUREMUS, ass!

Translation: I met a really hot girl last night whilst out drinking, and she came back to my place and everything, but then she turned out to be a dicktease (or pricktease)
4. Druse
