Extended definition
Getting "bust" means your session gets cut: security, a guard or the cops show up and you have to pack it in. A heavily "busted" spot is famous for how hard it is to skate without getting kicked, which adds epicness to landing the clip. It's everyday street life and part of its mythology: half the legendary videos were filmed running from the bust.
