1. A cop. This term is used when the cop is coming after you. Avoid cops at all costs, they are out to get you for something you did or did not do.
2. A grind done on a skateboard when one truck is on the rail, and the other is raised above.
5 0, 5 0, scatter!
Pack your shit, we're going to Canada. That 5 0 just busted our crack house.
Shit, did you see that 5 0 grind he did down that rail?
