"Al burro," EroCaddeo and Sky's "for a few" post: what does it mean?

"Butter." In the background, the Four Moors flag. And below: "For a few." And so this "mysterious" (but not for everyone, of course) post reposted by Sky on its official social media channels needs to be explained. It's the case of a hyper-localized, popular trash catchphrase becoming a slogan on the stage of one of the most watched shows: X Factor.

The driving force behind this media buzz is eroCaddeo, the competing artist from Sinnai who yesterday advanced to the next round with a powerful, personal performance of Tiziano Ferro's hit "Sere Nere."

The audience was ecstatic, with the inevitable waving of the Sardinian flag, confirming the validity of the competition (popular legend has it that without the Four Moors, a musical event gathering more than 20 spectators could not take place).

And this is the moment. Giorgia notices the flag and alerts eroCaddeo: "Look, there's your flag," she says. And he says: "Ciao Cagliari, al burro." An out-of-context expression, but only for those who aren't from Cagliari (or the surrounding area), don't frequent social media, or who in the last 10 years or more haven't seen a video from Pirri, Cagliari, or some other working-class neighborhood featuring the man known to everyone as "Checco." A protagonist of life on the margins, a sociologist who doesn't have time to find more in-depth definitions would say.

His videos had gone so viral that the step towards degeneration—and violence, not just psychological—was easy. That phenomenon has since stopped, thankfully. But the catchphrases and memes (as well as some graffiti) remain . "Al burro" (with butter) is one of the Cagliari character's nonsense expressions , which have become popular among young people of all ages.

Now it's over on Sky, with millions of viewers wondering what the hell it means. And luckily (for them) another must-have hasn't crossed the Tyrrhenian Sea: "Lillililalla."
