Anywhere there is potential of male or female nudity, be it a nude beach or a desert festival like Burning Man, etc. shirtcockers abound like environmental bedbugs, pests biting at an overall aura. While most shirtcockers manage to find viewing spots of the genitals on display such as behind the tree looking through their high-powered binoculars or behind trail rocks or outcroppings should the shirtcocker want to begin mindlessly stoking his junk as though he's in the privacy of his own boudoir, occasionally even a shirtcocker takes his eyes off the ball(s)/pubic hair on display. DO NOT MAKE EYE CONTACT WITH THE SHIRTCOCKER OR YOU WILL RUN THE RISK OF BEING INFECTED! Shirtcockers, like bats and raccoons, are known carriers of things like rabies, the plague and even the Serious Creeps.
We were walking to the beach when we saw that dude playing with himself behind the slide. Alison must have been shirtcocked, cause she got the Serious Creeps and took off running. Somehow through principals of a non-local universe, the shirtcocker is able to project sex crimes onto his victim simply through lines of sight.
