Is "tnetennba" a real word?

I've seen and heard the word "tnetennba" used, most famously by Moss in an episode of the IT Crowd in which he was a contestant on a fake episode of the TV show Countdown. In this episode, no definition of the word is given by when asked, Moss uses the word in a sentence as follows;

Good morning, that’s a nice tnetennba

I am trying to establish whether this is a real word or not, which is difficult since language is always changing. I've found multiple sites stating that the word was made up purely for the show and some others saying that the word itself is nothing more than a mechanism for generating traffic to a website, among others.

Is "tnetennba" a real word, and if so, what does it mean?

I'm afraid it's not a real word, and the inability to find it any dictionary will confirm that.

Richard Ayoade used the 9 letters on the countdown board in a humorous manner as, had it been a real word, it would have won.

The episode in question was not a "real" episode of Countdown - I believe it was an episode of The IT Crowd.

No, It hasn't been considered a real word so far.

Although you may find the word and its definition in some sites, it can't be found in any mainstream dictionary: Merriam-Webster, Oxford English Dictionary, etc. The moment you find "tnetennba" in such sources, you can affirm it is a real word.

Definition of "tnetennba". Meaning 1: A word whose function is purely to attract traffic to a website. Meaning 2: Someone who looks up words which have been artificially created for the purpose of fiction or comedy.

The entire point of that scene was that it is not a real word, but Moss managed to convince everyone on the show that his arbitrary string of letters was worth some points. That was the joke.

This question is based off of the understanding that there is such a thing as a "real" word. Most of the answers assume that a real word means something which has been officially recognized by some credentialed source. I am offering an alternative answer with a different assumption - a real word is one which communicates an idea effectively, regardless of credentials to be a "real" word. Credentialed sources simply document something that has already happened in "reality." I don't know the definition of tnetennba, but if it conveys an idea effectively to a group of people, it is a real word.
