Feh means disgust!?

So I was just gonna go into the FEH official website and I was kinda lazy so I just typed "feh" and I got a dictionary result.

"The greatest writer in the English language? Feh!"

I was laughing hard when this popped up. English is'nt my native language so I don't know if people always use this expression.
