Two teenagers stand face to face, surrounded by a crowd. They stare each other down and get ready to compete. But there are no punches here, no improvised rhymes and no traditional dance battle either. To win, you have to show who has more "aura".
The so-called "aura farming" battles have brought to the streets a language born on social media. Young people, mostly aged between 14 and 20, compete using gestures, poses and recreations of some of the most recognisable memes and viral videos on the internet.
