Why do so many teens/younger men here wear chains/necklaces?

It’s a random question I know, but having moved here recently - compared to my home country, I’ve noticed that just about every second young man or teenager wears a little chain or necklace around their neck. Is there some kind of cultural significance? Is it some kind of signifier of something? Is it a mark of coolness and popularity? I’ve never seen it before on this scale, and more than anything I’m just curious as to why they’re so common here!
