Person: "Do you like cheese?"
Person 2: "Yes but I think you'll find it's much nicer when you rub it all over your body first"
Everyone else: "Oh my God that's such a crapstain!"
The feeling one has when he or she feels as if they must use the restroom, and are approaching a known toilet. Most often felt in a car whilst en route to your home.
"Oh no! It's the crapitational pull! Drivefaster or I may burst!"
