Overview

Post-micturition convulsion syndrome, also known as piss shivers, pee shivers, peegasm or whiz willies, is a phenomenon in which one feels a shiver running down the spine following urination.^[1] The shiver can produce a brief twitch, which is a form of myoclonus.

To date, despite years of Internet discussion and theorizing, there is no agreed-on explanation of the phenomenon and no medical research into it. However, it has been mentioned occasionally in columns, and in one internet poll, where about 83% of males and 58% of females reported experiencing it.^[2]
