I'm not so bothered about knees hanging out, but what's with wearing jeans at half-mast with bottoms hanging out!
Please do not speak out against that particular fashion. The most famous opponent of low slung jeans was Bill Cosby, when he took time off from his busy schedule of drugging and raping women to tell other African Americans how terrible they were.
Just let the kids get on with it. They are going to dress and act in ways you find appalling. If your grandad was still around, I bet he could recount the horrors of your generation.
I feel the opposite, that when I see a trend I can't get on board it makes me feel old. Man buns, for example. Just an ugly look, especially combined with a Hitler Youth buzz cut. But they like it and their ladies like it, so I just admit quietly to myself I am old and I am grateful that now I finally have something to stop me fancying 23 year olds.
(the fashion springs from US gansta culture. No belts in prison. So they took that look outside, and it became a token of their power. Kids in the neighbour imitated it, and did the hip hop artists. The kids at Hebden Bridge? It's a token of their clique, plus it annoys people.)
