An informal, yet polite, way to excuse yourself from any situation where you must run and eradicate your cramping bowels of fecal matter because holding it is simply not an option.
Example 1:
Carl's Boss: Our third quarter profits were above expectation..............Yes Carl?
Carl: Sir I will be right back. I need to run for a Quick Pinch.
Carl's Boss: Understandable. As I was saying............

Example 2:
Sandy: Honey, please stop at the next gas station. I need to do a Quick Pinch. That meatloaf back at the diner we ate at is scooting through me.
