Ninja Turtle slice 

A large slice of pizza similar to that seen in the opening scene of Ninja Turtles II: Secret of the Ooze at Ray's Pizza. Typically a Ninja Turtle slice would be at least 1/5 or 1/4 of the entire pizza.

Dude, I just tried a new pizza place and they had ninja turtle slices.

Grinding the Turtle 

When you catch a kid trying to steal your basketball when you're working in your garage its what you tell them you were doing when you confront them about said alleged theft.

I was busy "grinding the turtle" when you came into my cul-de-sac and tried to steal that basketball!
