The Fine(or Fucking) Article

[shkkmo]

I always read the 'F' as "Featured"

Urbandictionary agrees. I reprogrammed myself to read it as "Fabulous" using a text replacement addon.

And this terminology (TFA) comes from at least the Slashdot days, about 20 years ago.

In turn, probably descended from “RTFM”—on Slashdot people who commented despite obviously not having read the article were told to “RTFA,” which eventually led to “TFA” as a general term to refer to the original article.

The "F" has always been "Forementioned" for me.
