The highest rating achievable for sphincter puckering during a high stress situation. The puckering may be so tight as to cause sphincter fluttering. Anything above Zulu is the complete loss of sphincter control. A Pucker Factor Zulu (PFZ) situation is commonly found in Near Death Experiences (NDE), although a NDE is not required. Items nearby, such as under garments, pants, seats, sofa cusions, etc., are often damaged during a full blown PFZ event, as the sphincter clamps down like a pitbull on a tire swing.
Dude! That near head on collision reached Pucker Factor Zulu. It was 5 minutes before my butt let go of the seat!
