When a male attempts to perform the act of urination and suddenly a turtle head approaches the end of the cave. Immediately rendering the urinater to pinch it off resulting in failing to push out the pee. This creates the same effect as stop and go traffic battling to push out urine and simultaneously pinch off a loaf.
Example 1: Damnit, i can't piss cause i'm too busy clenching cheek, stupid stop and go traffic.
