My grown-up friends don’t use based in its new slangy sense, so I asked Veronica (whom I still think of as a child) what it meant. ‘It’s a Millwall thing,’ she said, chanting: ‘No one likes us. No one likes us. No one likes us. We don’t care.’

I’m not talking about the established sense, as in based on fact (generally meaning ‘fictional’) or evidence-based (which entails choosing your facts), but about a usage that has jumped in the past decade from the hippity-hoppity world of Lil B to the fringe reality of the alt-right.
