When a man uses a urinal in a restroom but is unable to release his urine with the customary dick reveal due to
stage fright. After standing pee-less for 10-15 seconds a man will sometimes discharge saliva from his mouth to encourage his urine to
follow suit and discharge. This pee-less stand at the urinal is known as a "
shot cock violation" since it causes a reservation of the urinal for a non-pee activity.
Brian had held in his urine throughout the whole movie in order to not miss any scenes. He limped to he men's restroom where he found three pee-less men hogging the three urinals. After waiting
15 seconds and not hearing any streams of urine hitting the cakes, Brian yelled out "
shot cock violation" and one of the men hung his head in shame and slowly backed away from
the urinal exposing it for use while is pee-less cock also hung it's head in shame.
