When one takes a shit which puts you through so much pain that you take hold of the sides of the toilet seat, and raise yourself up about 1/2 inch and squeeze plastic and porcelain to try and take your attention away from the pain you are being dealt by the wide load leaving your body.
Person 1: That shit was huge!
Person 2: Seat Grabber?
Person 1: Yeah!
Person 2: Damn! You want the ice out of my Coke?
