"Hoodie-horror" is reportedly a "uniquely British [film] sub genre brought on by the fashion choices of youth trying to avoid the gaze of CCTV security cameras."
As Eden Lake and Harry Brown are classified as "hoodie-horror," I assume the horrific hoodies are hoodlums who wear hoodies and not hooded sweatshirts, but this hoodie-horror flick blurs the distinction:
Homonym-horror.
