A hard hat is the hard tip of a turd that is difficult to pass through the rectum. It is usually followed by super soft serve poop, or diarrhea.
Whew! That was one super tough hard hat! Glad I got that one out!
A construction type hard hat kept in the trunk of an automobile for shit emergencies allowing wearer "no questions asked" free access to tens of thousands of Porta Potties nationwide.
When I wear my emergency hard hat,I can use the Porta-John at any construction site and nobody gives me a second glance.
