p seat
The seat where the passenger sits and takes over the wheel when the driver is too busy doing stupid stuff like making a drink or rolling a joint.
My friend took over the p seat while I tried to make a drink. I ended up in a ditch.
The p seat is where my brother goes when he wants to drive and I'm too busy eating fries.
I took the p seat because my friend was too busy yelling at the radio to drive.
