"The street finds its own uses for things" describes a situation where things are used in unanticipated ways, which is one of the core aspects of hacking. Hacking isn't confined to computers, of course, there are life hacks and car hacks and food hacks and hacks for everything in between (even shopping carts apparently). While I'm not endorsing violence, I can't ignore the creative problem solving on display here.
