Britishism used to describe something outrageous or awesome.
Guy 1 - "The taco truck is in town." Guy 2 - "Proper Hardcore"
When something is so awesome, or old-school hardcore, it is Proper Hardcore. Proper Hardcore is also a britishism that cannot be said without a British accent.
Guy: That box of Cheerios was on sale, so I bought two instead of one! Dude: Proper Hardcore!
