ninja rock 

A ceramic fragment, usually from a broken spark plug, used to break car windows for petty thievery.

The ninja rock popped the cork on the brand new 540i, and we grabbed an ID and a checkbook.

ninja rock 

a ninja rock is a rock that sneaks up on you while walking or running and causes you to either twist, sprain, or break your ankle. At the very least it will make you say ouch that hurt. Most commonly happens at night when you cant really see whats on the ground so well.

I was walking to the chow hall with my roomies and out of nowhere this ninja rock made me twist my ankle.

Aww fuck damn ninja rock just tried to take me out. I hate those sneaky bastards.

Dude Caleb was walking to back from the store last night and stepped on a ninja rock. It put him on crutches man.

Ninja Rocks 

Small shards or pieces of ceramic spark plug insulator (the white part). When thrown at glass, they break it very quietly. They are used mostly for car burglaries in which the burglar wants to remain unheard.

Dan hit the driver's window with ninja rocks, then Joe ran up on the guy hit him in the nose after opening the door.
