Is "FiDi" the new "Colored"?

(By Eyleen Tavy)

Following a link on the always-excellent Eater SF's Board Wrap (they lurk so we don't have to), we came across this sterling remark: "A friend of mine who lives in the Financial District asked me not to call it FiDi."

What? We didn't know this was bad. We feel like the well-meaning folks who try to engage us when we go back home to Delaware, all "So how's it in San Fran?" Readers, what about it? Is "FiDI" the nabe equivalent of "Frisco", and we're too uncool to know, until now? Or is this forum poster's "friend" a bit, shall we say, of a prig?
