look up any word, like yeet:
adj. - describing the kind of guy that sits there and follows the score of a piece of music at a (classical) concert. Especially strong if it's some crazy avant-garde stuff.
"Dude - did you see the guy following that Varese piece in the back row? Seriously hardscore."

It is a combination of the words "Heatscore" and "Hardcore", it is something very heatscore but also very hardcore.
"Man throwing that desk off of a 7 story parkade right beside the police station was hardscore to the core"
"Your're Fucking Hardscore"
