What does "TFA" mean here please?

The featured article.

The article. Pick whatever adjective you like beginning with F!

I think it's "The fucking article".

Yes and to be clear, one uses "TFA" to imply annoyance that TFA hasn't been read.

e.g. "TFA covers this already."

That’s not something I wanted to imply. It can also stand for "the fine article". Is there a better shorthand for "the article linked at top of the page" / "the original article"?

The fucking article.
