Nail Cred
Nail Cred is the punishment you get for being a pain in the ass. The more you bug someone, the harder they’ll beat you up later.
My little brother got 5 Nail Cred for telling me I was ugly 10 times in a row.
I got 15 Nail Cred from my teacher for drawing on the whiteboard with my crayons.
My dad cashed in his Nail Cred and made me eat 10 hotdogs for breakfast.
