To be overly hardcore, that is, an individual whose is ridiculously extreme and over-the-top in everything they do. Their excessively intense mannerisms and personality manage to piss off anyone within the general area of this person.
"That guy is doing push-ups to impress those girls he met just 5 minutes ago, and he's totally creeping them out."
