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!
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...
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)
A Norwegian slang, meaning the act of doing something in a unstoppable way.
"Dude, your ma is hot!"
"Gonna druse your face, asshole!"
"Ready for some homework"
"Yeah, lets druse with pen and paper"
"Klar for fylla?"
"Ja, DRUSE PÅ!!"
