MCNAIR 

Used to declare dominance in regards to riding in the seat directly behind the front right seat in a vehicle. This is because that seat is behind the "shotgun" position.

4 friends walk up to a car.

Person 1: I call shotgun

Person 2: I call Mcnair

Person 3: damn, now I have to sit behind the driver.

This is because of how mcnair was behind a shotgun..
