Opposite of calling shotgun, that is, a witty response when your friend beats you to the passenger seat. A way of claiming the seat behind the passenger seat. Assures you will not be stuck in the bitch seat. Useful when riding with 3+ passengers. Also very useful when having a clambake to claim a comfortable seat.
