What the Fuuuuuu !!!

[Ishan Hokage]

Nowadays I'm often asked "What's the fuuug?"
They expect me to have a answer but I don't! They all think they live in a a damn meme!
So what is Fuuu, I once heard that the old japanese cultural anime often make use of this term to portray their anger.
I take deep interest in finding about these terms, I'll need help on this one.

Once I shouted it on the street to someone and got punched! What is this word that makes people so angry!
All I said was "you know what, fug you.!!?"
I'm completely clueless about this. Does anyone know the origin?
