Felony Hole

A hole or opening located on the floor of a vehicle where items (like drugs or illegal paraphernalia) can be thrown from the vehicle without being detected as easily. Looks like trash being driven over, not illegal items flying from your window.

Person 1: Dude, that car I bought had a felony hole on the passenger side.
Person 2: Well, we can toss out anything illegal if the police pull us over. It'll be like we drove over some random road trash.
