You know you're hardcore when after finishing your injection, you disassemble the pin and suck both the needle and syringe dry as a bone so as to not waste any of that sweet goodness - even with the non 17-aa's.
You know you're hardcore when after blowing a load on your girlfriend, you stare at your giz and are kind of pissed off that you wasted all that protein, which could have been used on your biceps instead.
You know you're hardcore when you see someone in a bar and, for no reason, punch them square in the face and say "Think about why I had to do that, motherfucker, think about it!"
