xkcd.WTF!?

Explanation ➲

The comic parodies a famous advertisement campaign for the Dos Equis beer brand. In the campaign, Jonathan Goldsmith plays "The Most Interesting Man in the World", a suave elderly gentleman with a number of astonishing life experiences and skills. The campaign's format generally includes the narrator presenting hyperbolic descriptions of the man's accomplishments, followed by the man delivering his signature catchphrase, "I don't always drink beer, but when I do, I prefer Dos Equis.", which has been widely adopted as an internet meme.

Cueball plays the antithesis of the protagonist in the campaign: the least interesting man in the world. Unlike the stories in the advertisement, his affairs tend to bore the listeners. Being the generic everyman, he possesses no outstanding capabilities at all. While the original is said to "speak French... in Russian", Cueball seems to have forgotten his French altogether. He also has apparently nothing of interest to tell, either in real life or in his blog. Instead, he will talk away about his weird dreams and his success in video games. Moreover, he is unable to stand too much beer and therefore absolutely ill-qualified to advertise it.

A superlative is a form of description that conveys the quality of being an extreme example (typically the most or least, in some way), and while the comic makes clear that this individual is not extraordinary in so many ways, his sheer blandness and lack of any exceptionalism is (in its own way) a very extreme position, hence the title describing this obviously unsuperlative individual as "Superlative", though there may be a small complication to this viewpoint that is related to the thwarted search for 'boring' numbers.

The title text is a reference to the slogan of the campaign "Stay thirsty, my friends." It also references Team Fortress 2 (TF2), a multi-platform, multi-player first-person shooter game.
